I asked 'A'isha about the Messenger of Allah's (ﷺ) voluntary prayers, and she replied: Before the noon prayer, he used to pray four rak'abs in my house; then would go out and lead the people in prayer; then come in and pray two rak'ahs. He would then lead the people in the sunset prayer; then come in and pray two rak'abs. Then he would lead the people in the 'Isha' prayer, and enter my house and pray two rak'ahs. He would pray nine rak'ahs during the night, including Witr. At night he would pray for a long time standing and for a long time sitting, and when he recited the Holy Qur'an while standing, he would bow and prostrate himself from the standing position, and when he recited while sitting, he would bow and prostrate himself from the sitting position, and when it was dawn he would pray two rak'ahs.

I did not see the Messenger of Allah (ﷺ) reciting (the Qur'an) in the night prayer in a sitting position, till he grew old and then he recited (it) in a sitting position, but when thirty or forty verses were left out of the Surah, he would then stand up, recite them and then bowed.

I asked 'A'isha whether the Messenger of Allah (ﷺ) observed (Nafl) sitting. She said: Yes, when the people had made him old.
