Prayer at Night (Tahajjud)
19/4. Chapter:
Leaving the night prayer by a patient
Sahih Bukhari
حَدَّثَنَا أَبُو نُعَيْمٍ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنِ الأَسْوَدِ، قَالَ سَمِعْتُ جُنْدَبًا، يَقُولُ اشْتَكَى النَّبِيُّ صلى الله عليه وسلم فَلَمْ يَقُمْ لَيْلَةً أَوْ لَيْلَتَيْنِ.
Narrated Jundab: The Prophet (ﷺ) became sick and did not get up (for Tahajjud prayer) for a night or two.
