Musannaf Ibn Abi Shaybah 17080 — A woman married to a man while she

Sayyiduna Umar (may Allah be pleased with him) said: If a man marries a woman who has leprosy, leucoderma or insanity, and he consummates the marriage with her, then the dowry (mahr) is due to her from the man because he made her private parts lawful for himself, and the compensation for it will be taken from the woman's guardian.
