Once Messenger of Allah 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) (Using translation from Bukhārī 4950)
اشْتَكَى رَسُولُ اللهِ ﷺ فَلَمْ يَقُمْ لَيْلَتَيْنِ أَوْ ثَلَاثًا فَقَالَتِ امْرَأَةٌ يَا مُحَمَّدُ إِنِّي لَأَرْجُو أَنْ يَكُونَ شَيْطَانُكَ قَدْ تَرَكَكَ لَمْ نَرَهُ قَرُبَكَ مُنْذُ لَيْلَتَيْنِ أَوْ ثَلَاثٍ فَأَنْزَلَ اللهُ ﷻ {وَالضُّحَى وَاللَّيْلِ إِذَا سَجَى مَا وَدَّعَكَ رَبُّكَ وَمَا قَلَى}
