Are you kidding me ? A society which doesn't leave any sort of sexual activities without committing them dares talk about incest ? And saying that one's cousin is "like" his sister doesn't make her his sister neither does adopting a person - which is forbidden in Islam by the way - make him your son . And although I asked someone some time ago about marrying a cousin and I was told there is nothing forbidding it , I'll wait and see the narration saying so .

Sir thanks a lot for your reply , @ sir osama abdallah but sir @ black muslim I was unable to understand what you were trying to say & I being a medical student agree with the previous answer that marrying with one's own cousin I.e the daughter or son of your father or mother's own sister or brother can cause adverse genetic effects on your offsprings
