It is narrated from Sayyidah Aisha (may Allah be pleased with her) that when the Messenger of Allah (peace and blessings be upon him) would return home after performing the Isha prayer, he would offer two rak‘ahs, then he would offer two rak‘ahs longer than those, after that the Messenger of Allah (peace and blessings be upon him) would offer three witr and would not separate them, then the Messenger of Allah (peace and blessings be upon him) would sit and offer two rak‘ahs, and their bowing and prostration would also be performed while sitting.
