Only those who request for help should be assisted

We should know that helping an oppressed does not become Wajib only when they request for help. Every person who is capable of removing difficulties of a believer must do so and if the needy person has entreated for assistance it becomes all the more important. As the Messenger of Allah (s.a.w.s.) says, 
"One who hears the entreaty of a man, 'O Muslims! Come for my help,' and does not assist him, is not a Muslim." 
(Wasaelush Shia)

Imam Ja'far as-Sadiq (a.s.) says, 
"If a person requests his Muslim brother to help him and the latter does not do so inspite of being capable enough; the Almighty Allah installs a huge snake from (the snakes of) Hell on his grave so that it can continuously bite him." 
(Mustadrak)

In another tradition it is reported that such a person will continue to receive this punishment till Qiyamat even if he had been pardoned (for other sins). Moreover, Imam (a.s.) also said, 
"No person refrains from helping and pleasing his Muslim brother unless there is some benefit in it." (i.e. his helping would have been sinful instead of rewarding)."

There are many traditions of this type from the Holy Imams (a.s.). Imam Sajjad (a.s.) says: 
"The sin which results in the descending of calamities is when one does not respond to the call for help of the helpless people." 
(Maani al Akhbaar)

Then the Imam (a.s.) invocated Allah saying, 
"O Allah! I plead for forgiveness for the time when someone is oppressed in my presence and I do not help him. I seek refuge in You for not helping an oppressed and a needy person." 
(Saheefa-e-Sajjadia)

Traditions on this subject are numerous and widespread. Let us be content with the ones we have discussed.

Helping the oppressed is not only for believers

Helping the oppressed is Wajib. This does not mean that it is Wajib only to help the oppressed believers. The commands of helping the oppressed in the light of Quran and traditions are only conditional as far as the capability of the helper is concerned. Even if the oppressed people are not Shias and they belong to other sects of Muslims, it is still Wajib to help them. Even if a non-offensive infidel is being oppressed, the command of enjoining good and forbidding evil dictates that he should be helped and the evil must be eradicated. There is an incident in Muntahiul Aamaal that Mansur Dawaniqi was in Mecca when an expensive diamond was brought to him. It was for sale. When Mansur saw the diamond he recognised that it had belonged to Hisham bin Abdul Malik and should have been surrendered to him (Mansur). Since Muhammad a son of Hisham was still alive he must have brought it for sale. So he ordered his guards to close all the doors of the Holy Mosque after morning prayers the next day, and allow the people to leave only from a single door after careful scrutiny. When Muhammad bin Hisham was found he should be arrested and brought to him.

When on the next day after morning congregational prayers all the doors were shut and it was announced that people should leave from one particular exit, Muhammad bin Hisham realised that it was a plot to arrest him. He became fearful and looked here and there in confusion and worry. He did not know what to do. Just then Muhammad bin Zaid bin Ali bin al-Husain (a.s.) came towards him and asked, "Who are you? And why are you so frightened."

"If I reveal my identity, would my life be safe?" 
"Yes!" he replied, "I take an oath to remove this danger from you."

"I am Muhammad, the son of Hisham Ibne Abdul Malik, Now tell who you are?"
"I am Muhammad Ibne Zaid bin Ali bin al-Husain (a.s.) and certainly your great grandfather Marwan had killed my father unjustly, but do not worry, you are safe. Taking your life will not avenge the innocent blood of my father and you had not killed my father yourself. Now I will try my best to save you from this danger. I have thought of a way out of this. I want you to co-operate with me and promise me that you will be absolutely fearless and repose your trust in me."

Thus, Muhammad bin Zaid covered the head and face of Muhammad ibn Hisham with his own robe and pulled him towards the exit beating him at every step. When they reached the exit he told the guard loudly, "This wretched man is a camel driver from Kufa. He had hired a camel from me but he ran away and he gave it to someone else. I also have two just witnesses to support my claim. You send your deputies with me and I will take him to the Qazi for judgement. Rabi, the chief guard ordered two of his deputies to accompany them and they came out of the Holy Mosque together. When they had walked for some distance Muhammad ibn Zayd told Muhammad bin Hisham, "There is still time for you to repent and promise to return my money, I will not trouble these guards and the Qazi if you assure me."

Muhammad bin Hisham picked up the cue and said, "O son of the Holy Prophet (s.a.w.s.). I promise to do as you say."

Muhammad bin Zayd told the guards that since the fellow has repented there was no need for them to take more trouble. The guards left them. Muhammad bin Hisham took off the robe from his face and kissed the face and head of Muhammad bin Zayd and said, "Allah the Almighty knew well where to put His message that He appointed the Prophet from your family."

Then he took out an expensive diamond from his pocket and requested Muhammad bin Zayd to accept it as a reward for saving his life but Muhammad bin Zayd declined saying, "I belong to a family that does not accept anything in return of a good deed. When I had condoned the murder of my father what value can this diamond have for me? I cannot take it."

The worshipper sinks in the ground

Shaykh Tusi has related from Imam Ja'far as-Sadiq (a.s.), "There was an old man of Bani Israel. He was praying when he saw that two children had caught a fowl and were pulling its feather. The fowl was shrieking in pain but he remained engrossed in prayers and did not help the poor bird by having it released from the clutches of the naughty children. So the Almighty ordered the earth to swallow this man and sucked him to the lowest depths." 

The worldly and the heavenly rewards for those who help the believers

A large number of traditions have reached us which emphasise the necessity of helping and assisting the believer and the rewards that are earned by those who do so. Let us study some of these traditions:
Imam Ja'far as-Sadiq (a.s.) said: 
"One who responds to the entreaties of his believing brother in difficulties and makes him glad and helps him and fulfills his needs; then seventy two bounties become occupant for him from Allah. One of these bounties is given to him in this world so that it can solve his worldly problems and the other seventy one are stored for him to remove the dread and difficulties of the Hereafter." 
(Wasaelush Shia)

He (a.s.) has also said: 
"If a person tries to fulfill the need of a believer and he completes it, the Almighty Allah writes in the scroll of deeds the rewards of a Hajj and Umra and Ihtikaaf of two months in Masjidul Haraam and fasts of two months. But if the need is not completely fulfilled the reward of one Hajj and Umra is written." 
(Al Amr bil Ma'roof)

Imam (a.s.) has also mentioned that it was revealed upon Hazrat Dawood (a.s.) that, 
"When one good deed of one of My servants reaches Me I shall grant him Paradise."

Dawood (a.s.) asked, "O my Lord what deed is that?" 
"Removing sorrow and difficulties of a believer, even if it is as little as giving him a date (fruit)!"

Dawood (a.s.) said, "It is only You O Allah! Who is of such greatness that once a person recognises You, he must never despair of Your Mercy."

It is quoted from Maimoon bin Mehram in the book Faqih, "I was sitting in the assembly of Imam Hasan (a.s.) when a person entered and said, 'O son of the Messenger of Allah. I am indebted to such and such person and now he wants to imprison me.'

Imam (a.s.) said, 
'I do not have any money to repay your debt.'

He said, 'Maybe you can speak to him so that he will not put me in prison.'

Imam (a.s.) arose and put on his shoes. I said, 'O son of the Messenger (s.a.w.s.) did you forget that you are in Ihtikaaf and cannot go out of the mosque?'

Imam (a.s.) said, 
'I have not forgotten, but I have heard my father say that the Holy Prophet (s.a.w.s.) had said, "One who tries to fulfill the needs of his believing brother is as if he has for 9000 years fasted during the days and prayed during the nights.'"

Letter of Imam as-Sadiq (a.s.) to the ruler of Ahwaz

When Najjashi assumed the rulership of Ahwaz there was a person in his service who requested Imam (a.s.) that, "I owe a certain amount to the ruler and he is a Shia, if you feel proper, please write to him regarding this matter."

Imam (a.s.) wrote: 
"In the Name of Allah, The Beneficent, The Merciful. Please your brother so that Allah may please you." 
(Usool al-Kafi)

The narrator says that when the person went to Najjashi, he was busy in some official matter. When he was free he handed Najjashi the letter saying that it was from Imam (a.s.). He kissed the letter and touched it to his eyes and asked, "What is the matter?" He told him that he owed some taxes. "How much?" Najjashi asked, "Ten thousand Dirhams," he replied. Najjashi called his accountant and told him to note down his debt as paid and close his account in the register. Then he went further and said that for the following year too this amount of taxes should be marked as paid. Then he turned towards him and asked, "Have I made you happy?"
"Yes!" replied the man.

Then he called for a horse, and a slave brought it. He ordered for a dress and gave to the man. At each step he kept asking, "Have I made you happy? Have I made you happy? The man kept replying "Yes! Yes! May I be sacrificed for you, Yes!" At last he told him to take even the carpet on which he was sitting. Because, he said, "It was on this carpet that you handed me this letter of my Master (a.s.), and if you have any other need, tell me." The man thanked him profusely, returned to Imam (a.s.) and related the details. The Imam (a.s.) was extremely pleased at the behaviour of Najjashi. The man asked, "O my Master are you pleased with Najjashi's response?"

Imam (a.s.) replied, 
"By Allah! Najjashi has also pleased Allah, His Prophet (s.a.w.s.) and his Progeny."

Yaqteen the father of Ali relates that one of the accountants of Yahya bin Khalid was appointed to collect tax from their area. Yaqteen says, "At that time I was owing a considerable amount of tax and if all the tax had to be cleared I would have had to sell off all my property. Some people suggested that he was a Shia, but I was too fearful to approach him in case he turned out to be a non-Shia and would force me to part with all my wealth, as I was a follower of Ali (a.s.). So I decided to run away from that place and headed for Mecca. After completing pilgrimage I decided to visit Madinah and presented myself before Imam Ja'far as-Sadiq (a.s.) and told him, 'Such and such person has been appointed as a tax collector but I was too scared toapproach him for the fear that he may not be one of your adherents.' Imam (a.s.) told me that there was no cause for me to worry and he wrote a brief note; 
"In the name of Allah the Beneficent, the Merciful, there are many people in His shade whose guardians are only those who remove the grief and difficulties of their brothers or give them opportunity or do some good to them even if it is as little as half a dried date and this person is your brother."

Imam (a.s.) put his seal at the end and handed me the note saying, 'Give this to him.' When I returned to my native town and went to his door, I said, 'I have been sent by Imam Ja'far as-Sadiq (a.s.).' He came running to the door barefooted. When he saw me, he saluted me and kissed my forehead and asked if his master has sent me. I replied in the affirmative and he said, 'If this is so, even my life is at your disposal.' He held my hands and implored me to tell him in what condition Imam (a.s.) was when I had departed. I told him that Imam (a.s.) was well. 'By Allah? Yes, By Allah?' he asked this three times and after that I handed him the hand-written note of Imam (a.s.). He kissed it and touched it to his eyes. Then he asked me what I wanted from him. I told him that I owed several thousand dirhams in taxes and I would spend my whole life in paying them. He called for my file and condoned the taxes payable by me and gave me a receipt. After this he called for his money chest and gave half of the money to me. Then he called for his horses and distributed them equally between us. After this he sent for his clothes and distributed them in the same way. When he had divided all his belongings and given me half he said 'O Brother! Have I pleased you?' Yes, I replied, 'By Allah!'

When it was the time for Hajj I said to myself that I could never repay his kindness except for that which is most liked by Allah and His Holy Prophet (s.a.w.s.). So I decided to go for Hajj in order that I may pray for him and after Hajj meet Imam (a.s.) and inform him of the kindness and request him also to pray for this noble soul. When I met Imam (a.s.) after Hajj he seemed very pleased and asked, 
"O Yaqteen how did that person behave with you?"

When I depicted his goodness the face of Imam (a.s.) beamed with happiness. I asked whether Imam (a.s.) was pleased with his actions? (so that Allah may please the noble man). Imam (a.s.) replied: 
"By Allah he has pleased my ancestors! By Allah he has pleased Amirul Momineen Ali (a.s.) and the Holy Prophet (s.a.w.s.) and he has pleased the Almighty Allah at the High Heaven."
