Silsilah as-Sahihah 452 — Both men and women can have wet dreams

It is narrated from Sayyidah Khawlah bint Hakim (may Allah be pleased with her) that she asked the Messenger of Allah (peace and blessings be upon him) about a woman who sees in a dream what a man sees (i.e., she experiences a wet dream)? The Prophet (peace and blessings be upon him) said: "There is no obligation of ghusl (ritual bath) upon her until there is emission, just as ghusl is not obligatory upon a man until there is emission."
