How they pray when there is an imam, a man and a woman

Sayyiduna Anas (may Allah be pleased with him) said: The Prophet (peace and blessings be upon him) led me and a woman of our household in prayer in such a way that I stood on his right and the woman stood behind him.

Thabit said: I prayed with Sayyiduna Anas (may Allah be pleased with him). I stood on his right, and his umm walad (a slave woman who had borne him a child) stood behind us.

Hisham said: I came to Urwah while he was praying, and there was a woman behind him. He made me stand on his right, and the woman was behind him.

Al-Hasan said: When the imam has one man and one woman with him, they should stand one behind the other. That is, the woman should be behind the man who is following.
