Sahih al-Bukhari 4950
Narrated Jundub bin Sufyan:
Once Allah's Messenger (ﷺ) became sick and could not offer his night prayer (Tahajjud) for two or three 
nights. Then a lady (the wife of Abu Lahab) came and said, "O Muhammad! I think that your Satan 
has forsaken you, for I have not seen him with you for two or three nights!" On that Allah revealed: 
'By the fore-noon, and by the night when it darkens, your Lord (O Muhammad) has neither forsaken 
you, nor hated you.' (93.1-3)
حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا الأَسْوَدُ بْنُ قَيْسٍ، قَالَ سَمِعْتُ جُنْدُبَ بْنَ سُفْيَانَ ـ رضى الله عنه ـ قَالَ اشْتَكَى رَسُولُ اللَّهِ صلى الله عليه وسلم فَلَمْ يَقُمْ لَيْلَتَيْنِ أَوْ ثَلاَثًا، فَجَاءَتِ امْرَأَةٌ فَقَالَتْ يَا مُحَمَّدُ إِنِّي لأَرْجُو أَنْ يَكُونَ شَيْطَانُكَ قَدْ تَرَكَكَ، لَمْ أَرَهُ قَرِبَكَ مُنْذُ لَيْلَتَيْنِ أَوْ ثَلاَثًا‏.‏ فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ ‏{‏وَالضُّحَى * وَاللَّيْلِ إِذَا سَجَى * مَا وَدَّعَكَ رَبُّكَ وَمَا قَلَى‏}‏
