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)  

اشْتَكَى رَسُولُ اللَّهِ ﷺ 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 ﷻ {وَالضُّحَى * وَاللَّيْلِ إِذَا سَجَى * مَا وَدَّعَكَ رَبُّكَ وَمَا قَلَى}  

A lady said, "O Messenger of Allah ﷺ! I see that your friend has delayed. (in conveying Qur'an) to you." So there was revealed: 'Your Lord (O Muhammad) has neither forsaken you, not hated you.' (93.1-3)  

قَالَتِ امْرَأَةٌ يَا رَسُولَ اللَّهِ مَا أُرَى صَاحِبَكَ إِلاَّ أَبْطَأَكَ فَنَزَلَتْ {مَا وَدَّعَكَ رَبُّكَ وَمَا قَلَى}
