It was narrated from Abu Salamah that :He asked Aishah about the prayer of the Messenger of Allah (ﷺ) at night. She said: "He used to pray thirteen rak'ahs. He would pray eight rak'ahs then pray witr, then pray two rak'ahs sitting down. When he wanted to bow he would stand and bow, and he prayed two rak'ahs between the adhan and iqamah of subh prayer
