'Abdullah bin Shaqiq al-'Uqaili reported: I asked 'A'isha about the prayer of the Messenger of Allah ( صلی اللہ علیہ وسلم ) . She said: The Messenger of Allah ( صلی اللہ علیہ وسلم ) would observe prayer (Nafl) in a standing position as well as in a sitting position, and when he commenced the prayer in a standing position, he bowed in this very position, and when he commenced the prayer in a sitting position, he bowed in this very position.
