Narrated Jundab bin `Abdullah:

Gabriel did not come to the Prophet () (for some time) and so one of the Quraish women said, "His Satan has deserted him." So came the Divine Revelation: "By the forenoon And by the night When it is still! Your Lord (O Muhammad) has neither Forsaken you Nor hated you." (93.1-3)

حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، قَالَ أَخْبَرَنَا سُفْيَانُ، عَنِ الأَسْوَدِ بْنِ قَيْسٍ، عَنْ جُنْدَبِ بْنِ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ احْتَبَسَ جِبْرِيلُ صلى الله عليه وسلم عَلَى النَّبِيِّ صلى الله عليه وسلم فَقَالَتِ امْرَأَةٌ مِنْ قُرَيْشٍ أَبْطَأَ عَلَيْهِ شَيْطَانُهُ‏.‏ فَنَزَلَتْ ‏{‏وَالضُّحَى * وَاللَّيْلِ إِذَا سَجَى * مَا وَدَّعَكَ رَبُّكَ وَمَا قَلَى‏}‏
