Abdullah bin Shaqiq (may Allah have mercy on him) says that I asked Hazrat Aisha (may Allah be pleased with her) about the voluntary prayers of the Prophet (peace and blessings be upon him), so she said that the Prophet (peace and blessings be upon him) used to pray four rak'ahs in my house before the Zuhr prayer, then he would go outside and lead the people in prayer, and after returning to my house he would pray two rak'ahs, then after leading the people in Maghrib prayer he would come home and pray two rak'ahs, then he would lead the 'Isha prayer and come to my house and pray two rak'ahs, at night he would pray nine rak'ahs in which witr was included, in the night prayer the Prophet (peace and blessings be upon him) would stand for a long time and sit for quite a while, the Prophet (peace and blessings be upon him) would recite and perform ruku' and sujood while standing and also recite and perform ruku' and sujood while sitting, and when the true dawn would appear he would pray two rak'ahs, then go outside and lead the people in the Fajr prayer.
