The Prophet ﷺ became sick and did not get up (for Tahajjud prayer) for a night or two.  

سَمِعْتُ جُنْدَبًا يَقُولُ اشْتَكَى النَّبِيُّ ﷺ فَلَمْ يَقُمْ لَيْلَةً أَوْ لَيْلَتَيْنِ  

Gabriel did not come to the Prophet (for some time) and so one of the Quraish women said, "His Satan has deserted him." So came the Divine Revelation: "By the forenoon And by the night When it is still! Your Lord (O Muhammad) has neither Forsaken you Nor hated you." (93.1-3)  

احْتَبَسَ جِبْرِيلُ ﷺ عَلَى النَّبِيِّ ﷺ فَقَالَتِ امْرَأَةٌ مِنْ قُرَيْشٍ أَبْطَأَ عَلَيْهِ شَيْطَانُهُ فَنَزَلَتْ {وَالضُّحَى * وَاللَّيْلِ إِذَا سَجَى * مَا وَدَّعَكَ رَبُّكَ وَمَا قَلَى}
