Once the Prophet ﷺ fell ill and did not offer the night prayer (Tahajjud prayer) for a night or two. A woman (the wife of Abu Lahab) came to him and said, "O Muhammad ! I do not see but that your Satan has left you." Then Allah revealed (Surat-Ad-Duha): 'By the fore-noon, and by the night when it darkens (or is still); Your Lord has not forsaken you, nor hated you.' (93) (Using translation from Bukhārī 4983)
سَمِعْتُ جُنْدُبًا يَقُولُ اشْتَكَى النَّبِيُّ ﷺ فَلَمْ يَقُمْ لَيْلَةً أَوْ لَيْلَتَيْنِ فَأَتَتِ امْرَأَةٌ فَقَالَتْ يَا مُحَمَّدُ مَا أَرَى شَيْطَانَكَ إِلَّا قَدْ تَرَكَكَ فَأَنْزَلَ اللهُ ﷻ {وَالضُّحَى وَاللَّيْلِ إِذَا سَجَى مَا وَدَّعَكَ رَبُّكَ وَمَا قَلَى} [الضحى 2]
