Malik said that a man who had committed fornication with a woman and the hadd-punishment had been applied to him for it, could marry that womans daughter and his son could marry the woman herself if he wished. That was because he had haram relations with her, and the relations Allah had made haram were from the relations made in a halal manner or in a manner resembling marriage. Allah, the Blessed, the Exalted, said, "Do not marry the women your fathers have married. " (Sura 4 ayat 21)
