It has been narrated on the authority of Aswad bin Qais who heard Jundub saying that Gabriel (علیہ السلام) delayed his visit to the Messenger of Allah ﷺ The polytheists began to say that Muhammad has been forsaken. At this Allah, the Glorious and Exalted, revealed: "Wadduha wal-laili iza saja, ma waddaka Rabbuka wa ma qala" [By the glorious morning light, and by the night when it is still: thy Lord has not forsaken thee, nor is He displeased].
