Musannaf Ibn Abi Shaybah

Hazrat Mak'hool and Hazrat Zuhri state that if a man marries a woman and then finds insanity, leprosy, vitiligo, or a disease causing hair growth in her private parts, he may return her because of these illnesses. However, the woman will receive her dowry, whether it is deferred or immediate. This dowry will be obligatory upon the person who encouraged the man to marry that woman.
