سنن ابن ماجه

It was narrated that ‘Abdullah bin Shaqiq Al-‘Uqaili said: “I asked ‘Aishah about the prayer of the Messenger of Allah (ﷺ) at night. She said: ‘He used to pray for a long time at night standing up, and for a long time at night sitting down. If he prayed standing, he would bow standing, and if he prayed sitting, he would bow sitting.’”
