Attributing an adopted child to the adopted father
Q: My uncle in law adopted my brother at the time of my brother's birth, and my uncle's wife breastfed him. Can my uncle be my brother's real father?
In my brother's nikah, if my uncle in law does not declare that he is the father, but the girl knows who the real father of the boy is, is the nikah correct?
Can my uncle in law write his name as the father of my brother?
