Hopelessness in Dua is Yaas

Many scholars believe that to discontinue invocation is a sign of despair. The hopeless person believes that he will not reach his destination through dua.

'Qunut' means that one accuses Allah of not being merciful and for not accepting his repentance. He thinks that whatever difficulties he suffers, are the retribution of his sins. Thus Imam Sajjad (a.s.) says in the 39th Dua of Sahifa-e-Sajjadiyah, "I neither despair of Your Mercy nor am I in despondence regarding you. But I am aggrieved because my good deeds are less in number and bad deeds numerous. Otherwise Your position is so high that not a single creature turns away dejected from you."

There is no doubt that despondence with regard to Allah is a Greater Sin. It is one of the characteristics of the polytheists and hypocrites as mentioned by Allah in Surah Fath.

"And (that) He may punish the hypocritical men and the hypocritical women, and the polytheistic men and the polytheistic women, the entertainers of evil thoughts about Allah..." 
(Surah Fath 48:6)

Skepticism Invites Punishment

The Holy Prophet (s.a.w.s.) announced from the pulpit

"By Allah who has no partner, He does not deprive any of the people from the blessings of this world and the hereafter. But he should not harbour doubts (about Him). He should have hope in Him and possess good morals. He should refrain from backbiting about the believers. I swear by Allah Who is the One and without partners, He does not punish a believer after he had repented and asked for forgiveness. Except those who are skeptical about Allah and lack in hope, have evil behaviour and indulge in backbiting about the believers. I swear by Allah except Whom no one is fit to be worshipped. When someone expresses reliance and trust in Allah; Allah who is extremely graceful, will not deem it fit to order anything contrary to the faith that the believer has reposed in him. Then you must have good thoughts regarding Allah and must always depend upon Him."
(Al Kafi)

Hope For Forgiveness and the Acceptance of Dua

Having good thoughts about Allah means that one should have the conviction that if he repents for a sin, Allah would forgive him. If he invocates, his prayer would be answered. If he does a good action, it is certain that Allah would accept it and reward him for the same. To hope in salvation is beneficial, and it is obligatory. However to hope for rewards without performing good actions is ignorance and conceit.

Hopelessness in the Affairs of This World and the Hereafter

Some scholars of religion explain that the detecting feature of 'Qunut' and 'Yaas' is that 'Qunut' denotes hopelessness with regard to the worldly blessings.

The Holy Quran says concerning this, 
"And He it is who sends down rain after they have despaired, and He unfolds His Mercy; and He is the Guardian, the Praised One." 
(Surah Shura 42:28)

Concerning 'Yaas' the scholars maintain that it is with regard to the affairs of the Hereafter, as mentioned in the verse:
"...indeed they despair of the Hereafter..." 
(Surah Mumtahena 60:13)

Qunut is Worse Than Yaas

To be despondent of Allah's Mercy results in the person being deprived of eternal blessings, because 'Qunut' causes the severance of the relation between the creature and Allah. The cause for this despondence is the extinguishing of the original flame of creation that had been alive in his heart. Even if a miniature of the light had remained, he would not have lost hope completely. It is possible that he may be involved in vain pursuits. If that is so then he has receded into the age of ignorance from the Mercy of Allah. But 'Yaas' denotes that the connection between the creature and Allah still remains even though separated by the curtain of sins. But behind the curtain the light of the original nature endures. He still believes in some connection with Allah. In such a case the dividing curtain could be removed.

'Yaas' can be forgiven but 'Qunut' does not deserve forgiveness. Thus 'Qunut' is included in the title of Shirk and becomes the greatest danger for man. (Quoted from Tafsir Ruhul Bayan)

Heedlessness to Allah's Anger and Retribution

One of the Greater Sins is a total disregard for Divine punishment. The person is fearless of the unseen retribution and scoffs at the idea of being punished for his actions. He lives blissfully in a world of material comforts and does not realise that he is fettered down by his sins. This is a Greater Sin. The Holy Imams, Imam Ja'far as-Sadiq (a.s.), Imam Musa Kazim (a.s.) and Imam Reza (a.s.) have classified the fearlessness of Allah's punishment among the Greater Sins. The Qur'an announces: 
"What! do the people of the towns then feel secure from Our punishment coming to them by night while they are asleep?" 
(Surah Araf 7:97)

"What! do the people of the towns feel secure from Our punishment coming to them in the morning while they play?" 
(Surah Araf 7:98)

"What! do they feel secure from Allah's plan? But none feels secure from Allah's plan except the people who shall perish."
(Surah Araf 7:99)

These three verses clearly prohibit the fearlessness of the punishment of Allah. The last verse mentions that those who do not fear Allah's punishment would be losers in the hereafter. Divine retribution will be their lot on the Day of Judgement, as will be the fate of the unbelievers and the non-repentant sinners.

It is clear from the Quran that to remain heedless of Allah's plan is a Greater Sin. Hence carelessness about the punishment and warnings of Allah is equivalent to disregard of His orders and prohibitions and an abject ignorance of His Supremacy. How can a lowly and insignificant being, now dare to oppose the Lord of the two worlds. This heedlessness and disregard is a Greater Sin that does not merit pardon, except that the sinner feels remorse and asks for forgiveness. It would emerge from the above discussion that whether a sin is pardonable or not depends more on the attitude of the sinner, rather than the sin itself. If in the innermost recesses of his heart, the transgressor is fearful of Allah, he is deserving of forgiveness, but if he is brazenly fearless of Allah's punishment, he is most unfit for pardon and mercy.

The plan of Allah means a sudden punishment that descends upon the sinners, as mentioned in the Divine book, 
"Does man think that he is to be left to wander without an aim?"
(Surah Qiyamat 75:36)

'Imla'- Respite

'Allah's plan' includes 'Imla'. From the time Allah created man it has been a Divine practice that the thankless ones and the sinners should not be punished for their sins immediately. Rather they are given a long respite. Since everyone is prone to sin except the Infallibles, if each one were to be punished for their misdeeds immediately, not a single person would remain on the face of the earth. Allah has stated in the Holy Qur'an, 
"And if Allah had destroyed men for their inequity, He would not leave on the earth a single creature, but He respites them till an appointed time..." 
(Surah Nahl 16:61)

Besides, Imla proves to be the Grace of Allah for the pious. It gives them time to reflect upon their behaviour, realise their mistakes, repent, and make a firm intention not to repeat their sins. Allah's indulgence thus helps them to achieve the good in this world and the hereafter. On the other hand indulgence shown to unrepentant sinners only makes them heedless of the fact that eventually they will be accountable for their deeds. They continue to commit one sin upon another and when their corruption reaches a limit, a sudden punishment descends upon them.

"And I grant them respite; surely My scheme is effective." 
(Surah Araf 7:183)

Disbelievers and sinners leading successful and comfortable lives may conceitedly feel that their capabilities have brought them success but in reality all that they have is a form of punishment from Allah and a sort of retribution which is referred to as 'the Plan of Allah."

Respite for the Wrong Doers

The Glorious Quran quotes thus, 
"And let not those who disbelieve think that Our granting them respite is better for their souls; We grant them respite only that they may add to their sins; and they shall have a disgraceful chastisement."
(Surah Aale Imran 3:178)

Imam Reza (a.s.) said, 
"By Allah, they have not been punished with anything more severe than Imla (respite)." (Safinatun Behaar)

Imam Sajjad (a.s.) has mentioned in Dua-e-Makarimul Akhlaq: 
"(O Allah). Give me such a life that my (long) life is spent in obedience to you. And when my life becomes a field of Satan take away my soul towards you (before I become eligible for Divine retribution)."

Istedraaj (Drawing Near)

Istedraaj is also included in Allah's plan. At times the respite granted by Allah also includes a new blessing. Allah bestows His bounties upon a person who has sinned so that he may feel ashamed of himself and make amends. Instead, the person often develops confidence and blatantly commits more sins. Such unfortunate people are mentioned in the following verse of Quran: 
"And (as to) those who reject Our communications, We draw them near (to destruction) by degrees from whence they know not." 
(Surah Araf 7:182)

It is recorded in Safinatul Behaar, "When Allah wishes good for a person and he commits a sin, Allah involves him in difficulties so that he may become aware that the cause of his problems is his own sin. He can then repent for it (immediately). When Allah wishes to punish a person who commits a sin, He gives him a new form of blessing so that he may be dazzled by the blessing and ignore repentance. This is what Allah means in the Ayat (quoted above)."

Istedraaj denotes failure to repent

When Imam Ja'far as-Sadiq (a.s.) was asked the meaning of "Istedraaj" he replied: 
"When a person commits a sin he is given respite and a new blessing, then when he fails to repent he is slowly led towards destruction; about which he is heedless. This is known as Istedraj and 'Allah's Plan." 
(Wasaelush Shia)

It is related from Amirul Momineen (a.s.) that he said: 
"Certainly, those who are given an increase in wealth and property by Allah, should not think anything but that it is Istedraaj. They should not be fearless (of Allah's plan). Because calm precedes storm."
