(16) باب قِيَامِ النَّبِيِّ صلى الله عليه وسلم بِاللَّيْلِ فِي رَمَضَانَ وَغَيْرِهِ
Narrated `Aisha:
I did not see the Prophet (ﷺ) reciting (the Qur'an) in the night prayer while sitting except when he became old; when he used to recite while sitting, and when thirty or forty verses remained from the Sura, he would get up and recite them and then bow. (ID)
