حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ وَمُحَمَّدُ بْنُ رَافِعٍ - وَاللَّفْظُ لاِبْنِ رَافِعٍ - قَالَ إِسْحَاقُ أَخْبَرَنَا وَقَالَ ابْنُ رَافِعٍ حَدَّثَنَا يَحْيَى بْنُ آدَمَ حَدَّثَنَا زُهَيْرٌ عَنِ الأَسْوَدِ بْنِ قَيْسٍ قَالَ سَمِعْتُ جُنْدُبَ بْنَ سُفْيَانَ يَقُولُ اشْتَكَى رَسُولُ اللَّهِ -صلى الله عليه وسلم- فَلَمْ يَقُمْ لَيْلَتَيْنِ أَوْ ثَلاَثًا فَجَاءَتْهُ امْرَأَةٌ فَقَالَتْ يَا مُحَمَّدُ إِنِّى لأَرْجُو أَنْ يَكُونَ شَيْطَانُكَ قَدْ تَرَكَكَ لَمْ أَرَهُ قَرِبَكَ مُنْذُ لَيْلَتَيْنِ أَوْ ثَلاَثٍ قَالَ فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ ( وَالضُّحَى وَاللَّيْلِ إِذَا سَجَى مَا وَدَّعَكَ رَبُّكَ وَمَا قَلَى)

It was narrated that Al-Aswad bin Qais said: "I heard Jundab bin Sufyan say: 'The Messenger of Allah (s.a.w) fell sick and did not get up to pray Qiyam (the late night prayer) for two or three nights. Then a woman came to him and said: "O Muhammad, I hope that your Shaitan has left you; I have not seen him approach you for two or three nights." Then Allah, the Mighty and Sublime, revealed (the words): "By the forenoon (after sunrise). By the night when it darkens (and stands still). Your Lord (O Muhammad (s.a.w)) has neither forsaken you nor hates you."
