fact that Allah has mentioned together gratefulness

The above verse is specially worth noting for the fact that Allah has mentioned together gratefulness towards Himself and to the parents. Certainly thankfulness to Allah is Wajib, and in the same way it is Wajib for the children to be thankful to their parents.

3) "And your Lord has commanded that you shall not serve (any) but Him, and goodness to your parents. If either or both of them reach old age with you, say not to them (so much as) "Uff" nor chide them, and speak to them a generous word. And make yourself submissively gentle to them with compassion, and say: O my Lord! Have compassion on them, as they brought me up (when I was) little. 
(Surah Bani Israel 17:23-24)

In this Ayat Allah has mentioned goodness to parents. In the same sentence He exhorts about service to Him. As service to Allah is Wajib, benevolence to parent is Wajib too.

When the Imam (a.s.) was asked to explain the meaning of the term "Bil Waledaine Ehsana" (and goodness to your parents), he said, 
"Be good to your parents and if they are in need of something, procure it for them before they ask for it."

Then the meaning of the words, "Taqullahuma Qualan Kareema" (speak to them a generous word) was explained by the Imam (a.s.)

"If the parents beat you, say 'May Allah forgive you'. The phrase 'Wakhfiz Lahuma' (and make yourself submissively gentle to them) is elaborated by the Imam (a.s.):
"Do not look at them with distaste. Do not raise your voice above theirs. When you walk with them do not precede them. When you go to a gathering, do not sit before they do. Never keep your hand above theirs (while giving them something)."

Service to Parents is Better Than Jehad

Imam Ja'far as-Sadiq (a.s.) narrates that a young man presented himself to the Holy Prophet (s.a.w.s.) and said that he wanted to participate in Jehad. The Holy Prophet (s.a.w.s.) told him:
"Certainly, go for Jehad in the way of Allah. If your are killed you will be alive near Allah and be provided sustenance from Him. The recompense for your sacrifice would be with Allah. If you return alive your sins would be washed off as if your were a newborn child."

This man said: "O Prophet of Allah, my parents are alive and they are aged and have great expectations from me. They do not like me to be away from them."

The Holy Prophet (s.a.w.s.) said:
"If that is so, then stay behind to serve your parents. By Allah in whose hands is my life, to serve parents for a day and night is equal to a year of Jehad."

Another tradition from Holy Prophet (s.a.w.s.) says:
"Acquire your place in Heaven by serving your parents. If you are guilty of 'Aaq' then make Hell your abode."

Goodness to Parents is the Expiation of Sins

Goodness towards the parents is the expiation of various sins. It is related in a report that a man came to the Holy Prophet (s.a.w.s.) and said, "O, Prophet of Allah (s.a.w.s.) there is not a single misdeed, that I have not committed. Is there repentance for me?" The Holy Prophet (s.a.w.s.) told him, 
"Go and do goodness to your father in order that your sins may be expiated."

When the man left the assembly the Prophet (s.a.w.s.) said,
"If his mother had been alive, it would have been more meritorious to do good to her."

Satisfaction of Parents is Satisfaction of Allah

The Holy Prophet (s.a.w.s.) has stated, 
"In the happiness of parents lies the happiness of Allah and in their dissatisfaction is Allah's dissatisfaction." 
(Behaarul Anwaar).

He (s.a.w.s.) further said, 
"A person who is good to his parents will be just a grade below the prophets in Heaven. And the Aaq-e-Waledain will be only a grade higher than the Firons in Hell." 
(Mustadrakul Wasael)

Angels Pray for Those Who do Good to Their Parents

Amirul Momineen Ali (a.s.) says, 
"Benevolence to parents is the greatest of the religious obligations."

The Holy Prophet (s.a.w.s.) says that Allah has two Angels one of whom says, "O Allah! Protect those who do good to the parents." The other Angel prays, "O Allah! Destroy those people by retribution, with whom their parents are angry." Needless to say, the prayers of the Angels are always accepted by Allah.

The Material Effects of Aaq

The previous traditions mention the ill effects of 'Aaq-e-Waledain' in the hereafter. The following traditions describe the evil repercussions of Aaq-e-Waledain in this life.

The last of the Prophets (s.a.w.s.) says: 
"There are three kinds of sins which are punished in this world, rather than being given respite till Qiyamat. The first is Aaq-e-Waledain. The second, injustice upon men and third, thanklessness for favour."

Hazrat Imam Muhammad al-Baqir (a.s.) stated, 
"Secret charity cools down Divine anger while goodness to parents and benevolence to relatives, prolongs life."
(Behaarul Anwaar).

Another tradition says, 
"Benevolence to parents and secret charity, ward off poverty, and both (these deeds) prolong life. Seventy types of death are kept away."
(Behaarul Anwaar)

"Those who assure me that they will be benevolent to parents and do good to the relatives, I will give them excess of wealth and a long life and assure them of being close among our group." 
(Mustadrakul Wasael)

Hazrat Imam Naqi (a.s.) said, 
"The displeasing of parents causes decrease in sustenance and degradation (also follows)."

Aaq-e-Waledain Cause Poverty and Misfortune

There was a young man from Madinah. His parents were very old. He never did any good towards them. He neglected them and did not expend any of his wealth for their well-being. After sometime he became a destitute and fell sick. Hiswretchedness and misery reached such excessive, that he became a pitiable character. The Holy Prophet (s.a.w.s.) said, 
"Those who cause hurt to their parents should derive lessons from the life of this man. See how his wealth and property has been taken away. His affluence and independence has changed to poverty and his health has turned into disease. Whatever position he was to get in Heaven, he has been deprived of due to his sins; in its place the fire of Hell has been prepared for him." 
(Safinatul Bihar)

Imam Ja'far as-Sadiq (a.s.) narrates:
"When Hazrat Yaqoob (a.s.) went to Egypt to meet his son Hazrat Yusuf (a.s.), he (Yusuf a.s.) did not alight from his horse to pay respect to his father. Hazrat Jibraeel (a.s.) descended, and told Hazrat Yusuf (a.s.) to open his fist. As he did so, a light shot out from his palm and rose towards the sky. Hazrat Yusuf (a.s.) enquired, "What was this light which came out of my hand and shot to the sky?." Jibraeel (a.s.) replied, "The light of Prophethood has departed from your loins. You did not pay due respect to your father hence none of your descendants will get Prophethood." It is true that Hazrat Yusuf (a.s.) did not descend from his horse to pay respect to his father. However, this was not due to any feelings of pride and vanity. The Prophets are sinless and could never harbour such emotions. His intentions were merely to maintain his dignity as a King among his subjects."

Evil Consequences of Aaq-e-Waledain

Aaq-e-Waledain brings disgrace in the Hereafter, and goodness to parents brings honour and glory. As Imam Ja'far as-Sadiq (a.s.) has said, 
"Those who wish an easy death should do good to the relatives and be kind to parents. When one does this, Allah will make easy the agony of death. In this world he will not face difficulties and poverty." 
(Safinatun Bihar)

Prayers of the Parents Are Accepted Soon

The supplication of parents for the welfare of the child are quickly answered by Allah and in the same way their ill wish (curse) due to displeasing them also takes quick effect. Numerous traditions have been recorded in this connection. One such tradition is connected with the merits of Dua-e-Mashlool. It is said that a young man had lost the use of his right hand which was paralysed due to the curse of his father. After his father's death, the man prayed the entire night, continuously for a period of three years in Masjidul Haram. One day Hadhrat Ali (a.s.) saw him and took pity upon him. He taught him Dua-e-Mashlool. By the virtue of this Dua the young man was cured.

The Mother Has More Rights Than the Father

Goodness towards the mother is more rewarding. The Holy Prophet (s.a.w.s.) emphasized that benevolence shown to the mother should be three times the magnitude of that shown towards the father. When he was asked as to which of the parents had more rights, he replied,
"Was it not your mother who suffered the birth pangs to give birth to you and provided you with your natural diet from her breasts? Indeed the rights of a mother far outweigh those of the father." 
(Mustadrakul Wasael)

Rights of the Parents

Someone asked the Holy Prophet (s.a.w.s.) about the rights of the father. He (s.a.w.s.) replied, 
"He should be obeyed always, as long as he lives."

Then he was asked, "What is the right of the mother?". He answered, 
"If the service to a mother equals the quantity of the particles of sand in the desert and the drops of rain on earth, it (this service) will not repay for a single day that she kept you in her womb." 
(Mustadrakul Wasael)

A Young Man and His Invalid Mother

It is reported that a young man approached the Holy Prophet (s.a.w.s.) and asked, 
"O Prophet of Allah (s.a.w.s.), I have a mother who is an invalid. She cannot even move by herself. I carry her on my back and feed her with my hands. I also clean her excreta. Have I fulfilled her rights?"

The Holy Prophet (s.a.w.s.) replied, 
"No. Because you have remained in the womb for a long period during which you derived your nourishment from her body. She was every busy in caring and protecting you at all costs. Inspite of such hardships she always wished a long life for you. But you are waiting for her to die so that you may relieved of the responsibility of taking care of her."

The Holy Prophet (s.a.w.s.) described the eminence of a mother's position in the following statement:
1) "If you are praying a mustahab prayer and your father calls you, do not break your prayer but if your mother calls, break the prayer."

Truly, this assigns a remarkably high status to a mother. The Prophet (s.a.w.s.) states, 
"Paradise is at the feet of your mother."

Hence one need not go far in search of Paradise.

Be Good to Parents Even if They Are Kafirs

Whether the parents are believers and pious or Kafirs and sinful, goodness towards them is wajib. And 'Aaq-e-Waledain' is Haraam.

The verse of Surah Luqman says thus, 
"And if they contend with you that you should associate with Me what you have no knowledge of, do not obey them, and keep company with them in this world kindly...". 
(Surah Luqman 31:15)

Dua For Sunni Parents

Moammar Ibne Khallad asked Imam Reza (a.s.) whether one is allowed to pray for one's parents if they had not followed the truth and had not been Shia.

Imam Reza (a.s.) replied, 
"If they are dead, pray for them and give Sadaqah on their behalf. If they are alive keep them happy."

The Holy Prophet (s.a.w.s.) says; 
"Allah the Most High has sent me as the Mercy for the worlds, except to the 'Aaq' (of parents)."

Jabir Ibne Abdullah (r.a.) reports that someone asked Imam Ja'far as-Sadiq (a.s.), "My parents are against the truth, i.e. they are not the Shia of Ahlul Bayt (a.s.)". Imam replied: 
"Be good towards them like you would be towards out Shias." 
(Al Kafi)

Momin and Kafir Are Equal Under Three Circumstances

Hazrat Imam Muhammad al-Baqir (a.s.) said; 
"Allah has not given superiority to a Momin in three circumstances.

First, to return what has been entrusted to you for safe keeping whether it belongs to a Momin or a Kafir.

Second, fulfilling an oath, whether given to a Momin or a Kafir. Third, doing good to the parents, whether they be Momin or Kafir." 
(Al Kafi)

A letter on various aspects of Islamic Shariat, written by Hazrat Imam Reza (a.s.) to Mamun, include the following:
"Benevolence to parents is wajib even if both of them are 'Mushrik'. However obedience to parents is not wajib if their order is against the orders of the Creator." 
(Oyun-e-Akhbare Reza)

Advice of Imam as-Sadiq (a.s.) to Zakaria Ibne Ibrahim

Zakaria, the son of Ibrahim, was a Christian. Later he converted to Islam and had the honour of meeting Imam Ja'far as-Sadiq (a.s.). He told Imam (a.s.) "My mother is a Christian and she is old and blind." The Imam advised him, 
"Serve your mother and behave kindly towards her. Upon her death, do not leave her dead body to others. Perform her funeral rites yourself."

Thus this statement of the Imam (a.s.) is pregnant with two prophecies. Her death, and her conversion to Islam.

When Zakaria returned to Kufa he began to behave very kindly with his mother. He fed her with his own hands. Changed her clothes, washed and bathed her too. In short, he served his mother in every possible way. His mother asked, "My son you were not so dutiful when you were a Christian. Why is it that now you serve me day and night?"

Zakaria replied, "O my mother. I have a master who is the son of the Prophet of Allah (s.a.w.s.). He advised me to serve you in this way." The mother asked, "Is he a prophet?" "No. But he is a son of the Prophet (s.a.w.s.)." "Such a person must be a Prophet because only prophets teach such manners." The mother remarked.

Zakaria explained to his mother, "The chain of the Prophets came to an end with the Prophet of Islam (s.a.w.s.). He was the seal of the Prophets. The one who has guided me is the son of the Prophet (s.a.w.s.)." The mother said, "My son, the religion of Islam that you have embraced is better than all the religions. Teach me, so that I too may become a Muslim."

So, Zakaria made her recite the 'Kalima' and taught her the true beliefs. Later, this lady performed the Zohrain and the Maghrebain prayers. The same night death approached her. She told her son: "Dear son, repeat to me again whatever you have taught me." Zakaria began to recite while she listened carefully and in this way she passed away.

Displeasing the parents is Haraam and goodness towards them is Wajib, whether they are alive or dead. In other words parents have rights upon their children even after they (the parents) are dead.

If the son or the daughter forgets the parents after their death and does not perform good deeds on their behalf, it is 'Aaq-e-Waledain' irrespective of the fact that the child had fulfilled all his or her rights and served them till the time of their death.

Rights of Parents After Their Death

First: To carry out the Wajib acts which they did not perform during their life time, like Namaz, Roza, Hajj and repayment of debts.

Second: To Act on their will and testament.

Third: To perform various good deeds for their salvation, i.e., to give Sadaqah, to perform charitable acts, and to carry out recommended acts on their behalf. In short, one should strive to the utmost in doing good deeds on their behalf so that Allah may shower His blessing and mercy on them.

The Disobedient Children After the Death of Their Parents

It is narrated from Hazrat Muhammad al-Baqir (a.s.):
"Certainly, if a person is good to his parents when they are alive but forsakes them after they die and does not repay their debts or pray for their forgiveness, Allah will record 'Aaq-e-Waledain' in the account of his deeds. On the other hand, if a person is 'Aaq-e-Waledain' when they are alive but after their death repays their debts and prays for their forgiveness and salvation, Allah will include him among the righteous people".

Single Action, Multiple Rewards

Hazrat Imam Ja'far as-Sadiq (a.s.) said, 
"What prevents you from serving your parents in their life and death? The Holy Prophet (s.a.w.s.) remarks about the goodness to parents after death. "Perform their 'namaz' (if some wajib prayers have been omitted by them, the eldest son should perform them himself, or have them fulfilled by someone else on payment. However, if no wajib prayer is remaining upon them, then he could pray Nawafil Namaz for them or have them performed on payment.) Pay Sadaqah on their behalf. Complete their Qaza fasts and fulfill the obligation of their Hajj. Whatever you do, both of you will be rewarded (i.e.you and your parents).

Apart from this, goodness to parents carries double rewards. One for the action itself, and second for the benevolence towards the parents.

Praying (Dua) For the Parents and Seeking Forgiveness On Their Belief

It is narrated from the Holy Prophet (s.a.w.s.) that a man approached him and asked whether his parents have any rights upon him after their death? The Holy Prophet (s.a.w.s.) replied, 
"Yes, pray Namaz for them, seek forgiveness on their behalf, respect their tradition, and be good to their relatives." 
(Al Kafi)

When is Obedience to the Parents Wajib?

The orders and restraints of the parents are of no significance with respect to the wajib acts and the Divine prohibitions. For example if the parents order the child to drink wine or restrain him from the obligatory prayers and fasts, they should not be obeyed. It is expressly mentioned in this Verse of Surah Luqman: 
"And if they contend with you that you should associate with Me what you have no knowledge of, do not obey them..." 
(Surah Luqman 31:15)

The traditions also support this Ayat: 
"No Obedience of a creature in contravention to the Divine command." 
(Behaarul Anwaar)

Apart from these circumstances, obedience to parents is obligatory with regards to the Makruh and Mubah acts. The same applies to the Wajib-e-Kifai.

If by performing these actions, the parents are displeased or hurt, it is 'Haraam', a Greater Sin and causes one to be 'Aaq-e-Waledain'. Suppose the son wishes to proceed on a non-obligatory journey and the parents restrain him as they fear some harm for him, or because they cannot bear to be separated from him; and the son disobeys them and goes ahead with the journey, such a journey is Haraam. It is a journey of sin. Salaat and Fasting is not Qasr for this journey. In short, anything that causes displeasure and hurts the parents, is absolutely Haraam.

Obedience to parents is not obligatory in the following cases:
When it causes unbearable hardships or harm. For instance, if they restrain the son from marriage when he feels the need for it. Or they order the son to divorce his wife without a sound reason. If such an action will result in harm to both the spouses, it is not obligatory to obey the parents.

As far as I know, it is not obligatory to obey parents even in cases where they do not get angry or hurt if their commands are disobeyed.

As far as possible one should obey their orders and restrain from opposing them. Especially when the parents advise their children for their own benefit and without any selfish motive.

Disagreement among the Parents

If a situation arises when there is a disagreement between the parents on any subject, as far as possible, one should try to pacify and satisfy both of them. However, if it is not possible then the wish of the mother should be given precedence.

We have already seen the reasons why her rights far exceed those of the father. She is also more deserving of obedience because being a woman she is more sensitive in comparison to men. The mother is easily disturbed by the slightest hurt caused by her child. She becomes restless and uncontrollable due to her motherly feelings. In contrast, the father exercises reason and intelligence and being less emotional, is much less affected. He would realise that the son is obeying the mother because of the very special status granted to her by Allah and not because he intends to disobey his father due to disregard for him.

Permission of the Parents is Necessary

The Islamic Shariat has prescribed certain matters wherein it is necessary to obtain the permission of both the parents. Or at least of one of them. For example, the Wajib-e-Kifai acts like Jehad, or the Mustahab acts like the recommended fasts, or matters like taking an oath, vow and promises. In all such cases it is Wajib to obtain the parents' permission. The First Martyr1 had mentioned ten topics on the rights of parents in his book "Qawaid". It will be appropriate to mention them.

Journey of the Child and the Martyr's viewpoint

1) Mubah and Mustahab journey without the permission of parents is Haraam. However a business journey and the journey undertaken for acquiring knowledge is allowed according to some Mujtahids.

2) Some Jurists are of the opinion that, obedience to parents is Wajib upon the child in every condition where there exists a doubt. Hence if the parents order their son or daughter to eat with them, and if there is doubt regarding the food, it is incumbent to obey the parents. Because, obedience to parents is Wajib while avoiding food in case of doubt, is Mustahab.

3) If it is time for prayers and the parents would like to get some work done, it is necessary to carry out the orders before offering Namaz. Here again the offering of Namaz at the earliest is Mustahab whereas the obedience to parents is Wajib.

Refraining From Namaz-e-Jamat

1) Parents cannot prevent their child from performing Namaz in congregation unless it causes some problem to them. For example, the absence of the son, while he goes for Fajr or Isha prayers, may cause them anxiety regarding their own securityor the safety of their property. Or, it may make them apprehensive about the son's safety.

2) If it is not absolutely obligatory (Wajib-e-Aini) the parents can stop their son from going on Jehad.

3) Regarding the commands, which are Wajib-e-Kifai, the parents can prevent their son or daughter only if there is a certainty or a chance of the Wajib being fulfilled by other people.

4) Some jurists are of the opinion that if one is praying a recommended prayer, he can interrupt it if his parents call him.

5) One must forgo recommended fasts if the father disallows them.

6) In the matter regarding vows and promises, if the parents are against it, then one must not disobey them.

7) It is the duty of the son to ensure that he causes no harm to his parents. And if someone else intends to harm them, the son must do everything in his capacity to ward off the harm.
