Question: What are the religious and worldly benefits of istighfaar?
Response: The benefits of istighfaar are that when a person seeks forgiveness by turning to his Lord honestly and sincerely – and assumes well of Allaah عز و جل, then indeed Allaah سبحانه و تعالى will forgive his sins, as Allaah (Tabaaraka wa تعالى) says:
{Say, “O My servants who have transgressed against themselves [by sinning], do not despair of the mercy of Allaah . Indeed, Allaah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful.”} az-Zumar 39:53
And when Allaah forgives him his sins, and he fears Allaah سبحانه و تعالى – then from the benefits of that is Allaah تعالى will facilitate his affairs with ease, and will provide for him from where he does not expect; just as Allaah (Tabaaraka wa تعالى) says:
{And whoever fears Allaah – He will make for him of his matter ease.} at-Talaaq 65:4
And He [also] says:
{And whoever fears Allaah – He will make for him a way out. And will provide for him from where he does not expect.} at-Talaaq 65:2-3
