Hazrat Jundub bin Sufyan (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) fell ill and for two or three nights he did not get up (for Tahajjud prayer). Then a woman (the wife of Abu Lahab, ‘Auwra’) came and said,“O Muhammad! I think your devil has forsaken you. For two or three nights I have seen that he has not come to you.”Upon this, Allah the Exalted revealed Surah Ad-Duha… that is,“By the morning brightness, and by the night when it grows still, your Lord has not forsaken you, nor is He displeased with you…”to the end.
