Can a brother and sister get married in Islam?
If you read closely all the answers from these Islamic readers you will get two things. One: You may not marry your sister of your mother or father. Two: You may marry your sister or brother if the father has not married the mother. So, of we look at this closely we will find the following. Man A marries woman B. She has a son. Man A sleeps with woman C and she has a daughter. There is no marriage and therefore, if man A wanted to marry his daughter he could do so. Also, if man A's son wants to marry his sister from woman C he may, because his father and her mother was never married. Even in Mose's law, it says that a man should not have sex with his sister. Under Jewish law, if he marries his sister, then he and she is cast out of the family. He loses all of his birth rights, while she still remains a part of the family, or able to say she is the daughter, while he has no one and cannot be helped by his family. Under Jewish law, if you are the eldest son and marry your sister, then you would really be in trouble, but you would be married.
