It was narrated that ‘Aishah said: “The Prophet (ﷺ) used to recite Qur’an sitting down, then when he wanted to bow he would stand up for as long as it takes a person to recite forty Verses.”

It was narrated that ‘Aishah said: “I did not see the Messenger of Allah (ﷺ) offer any of the night prayers in any way other than standing, until he became old. Then he started to pray sitting down until, when there were thirty or forty Verses left of his recitation, he would stand up and recite them, and prostrate.”
