Q: I married the daughter of my full-brother's daughter. However, I did not consummate the marriage. She stayed in her father's house after we concluded the marriage contract; because she was very young at the time. I intended to consummate marriage after she reaches the age of puberty but a religious scholar told me (Part No. 18; Page No. 201) that this marriage is not permissible. He quoted as evidence Allah's saying (Exalted be He) on the women who are not lawful for a person to marry: Forbidden to you (for marriage) are: your mothers, your daughters to His saying: ...your brother’s daughters He added that marrying my brother's daughter or her descendants is unlawful for me. After that I consulted another scholar who told me that there is no evidence to support the view of anyone who says that my marriage contract is invalid. Therefore, I am writing to you hoping that you will send me a written Fatwa as regards the ruling on this marriage.
