Gabriel (peace be upon him) said to the Messenger of Allah (peace and blessings be upon him): Indeed, Allah has spoken good words to you and your ummah when this verse was revealed: "The Messenger has believed in what was revealed to him from his Lord, and [so have] the believers. All of them have believed in Allah..." So ask, and you will be given. Then the Prophet (peace and blessings be upon him) asked: «لَايُكَلِّفُاللَّهُنَفْسًاإِلَّاوُسْعَهَا» until the surah was completed with the supplication of the Prophet (peace and blessings be upon him).
