Narrated Sa'id bin al-Musaiyab: 'Umar bin al-Khattab (RA) said: "If any man married a woman and after sleeping with her finds that she is affected with leprosy or insane, she gets her dowry (if he divorces her) for having intercourse with her, and it is returned to him from the one who has deceived him with her." [Sa'id bin Mansur, Malik and Ibn Abu Shaibah reported it. It's narrated are reliable (thiqah)] . Sa'id (bin Mansur) also reported something similar from 'Ali (RA) and added: "And (if) she has something like a horn (Qarn) (coming out of her vagina), her husband then has the right to divorce her or keep her. And if he had intercourse with her, she gets her dowry for the intercourse her husband has had."

Narrated Sa'id bin al-Musaiyab this Hadith also: 'Umar (RA) gave a decree regarding a husband who is impotent that he must be given delay for one year. [Its narrators are reliable] .
