Yahya related to me from Malik from Yahya ibn Said that Said ibn al-Musayyab had said that Umar ibn al-Khattab said, "If a man marries a woman who is insane, or has leprosy or white leprosy, without being told of her condition by her guardian, and he has sexual relations with her, she keeps her bride-price in its entirety. Her husband has damages against her guardian."
