Musannaf Ibn Abi Shaybah 887 — A woman who sees in her sleep what

Sayyidah Umm Sulaym asked the Prophet (peace and blessings be upon him): "O Messenger of Allah! If a woman sees in her dream what a man sees, is the ritual bath obligatory upon her?" He said: "Does she feel desire?" She said: "Perhaps." The Prophet (peace and blessings be upon him) said: "Does she see wetness?" She said: "Perhaps." The Prophet (peace and blessings be upon him) said: "Then she should perform the ritual bath." Later some women met Sayyidah Umm Sulaym and said: "You have disgraced us before the Messenger of Allah (peace and blessings be upon him)." She said: "By Allah, I was not going to stop until I knew whether I am in what is lawful or in what is unlawful."
