Arfajah al-Thaqafi (may Allah have mercy on him) says that Sayyiduna Ali (may Allah be pleased with him) used to order the people to perform the night prayer of Ramadan, and he appointed a separate imam for the men and a separate imam for the women. Arfajah (may Allah have mercy on him) says: I was the imam of the women.
