The Book of Qiyam Al-Lail (The Night Prayer) and Voluntary Prayers During the Day
(18)
Chapter: What is done when one begins the prayer standing and mentioning the differences with those who reported from 'Aisha concerning it
(18)
باب كَيْفَ يَفْعَلُ إِذَا افْتَتَحَ الصَّلاَةَ قَائِمًا وَذِكْرِ اخْتِلاَفِ النَّاقِلِينَ عَنْ عَائِشَةَ فِي ذَلِكَ
It was narrated that 'Aishah said:
"The Messenger of Allah (ﷺ) used to pray for a long time at night. If he started to pray standing, he would bow standing and if he started to pray sitting, he would bow sitting."
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ بُدَيْلٍ، وَأَيُّوبَ، عَنْ عَبْدِ اللَّهِ بْنِ شَقِيقٍ، عَنْ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُصَلِّي لَيْلاً طَوِيلاً فَإِذَا صَلَّى قَائِمًا رَكَعَ قَائِمًا وَإِذَا صَلَّى قَاعِدًا رَكَعَ قَاعِدًا ‏.‏
