Sayyiduna Anas (may Allah be pleased with him) narrates: Sayyidah Umm Sulaym (may Allah be pleased with her) asked the Noble Prophet (peace and blessings be upon him) about a woman who sees in a dream what a man sees (i.e., the woman experiences a wet dream). The Noble Prophet (peace and blessings be upon him) said: When a woman has an emission, she should perform ghusl (ritual bath).
