Question

Where is this quote from?

Answer

Abu Dharr reported Allah’s Messenger (may peace be upon him) as saying that Allah, the Exalted and Glorious, said: My servants, I have made oppression unlawful for Me and unlawful for you, so do not commit oppression against one another. My servants, all of you are liable to err except one whom I guide on the right path, so seek right guidance from Me I shall direct you to the right path. O My servants, all of you are hungry except one whom I feed, so beg food from Me, so that I may give that to you. O My servants, all of you are naked (need clothes) except one whom I provide garments, so beg clothes from Me, so that I should clothe you. O My servants, you commit error night and day and I am there to pardon your sins, so beg pardon from Me so that I should grant you pardon. O My servants, you can neither do Me any harm nor can you do Me any good. O My servants, even if the first amongst you and the last amongst you and even the whole of human race of yours, and that of jinns even, become Upon the heart of the most God-conscious  person amongst you, nothing would be added to My Power. O My servants, even if the first amongst you and the last amongst you and the whole human race of yours and that of the Jinns too in unison become like the heart of the single most wicked person, it would cause no loss to My Power. O My servants, even if the first amongst you and the last amongst you and the whole human race of yours and that of jinns also all stand in one plain ground and you ask Me and I grant every person what he asks for, it would not cause any loss to Me except how much loss a needle causes when is is dipped into the ocean  . My servants, it is your actions which I am recording for you then I shall reward you for them, so he who finds good should praise Allah and he who does not find that should not blame anyone but his ownself. (Sahih Muslim
