Abdullah bin Shaqiq (may Allah have mercy on him) says that I asked Sayyidah Aisha (may Allah be pleased with her) about the voluntary prayers of the Messenger of Allah (peace and blessings be upon him). She said: He used to pray four rak'ahs in my house before Dhuhr, then he would go out and lead the people in prayer, then return to my house and perform two rak'ahs.
