Q: I am asking this question on behalf of my friend. He is married and got 2 kids. His wife got postnatal depression and he is thinking of marrying his wife’s sister so she can lookafter his kid. Is it allowed in Islam to marry one’s wife’s sister?
A: It is not permissible to marry two sisters at the same time.
And Allah Ta’ala (الله تعالى) knows best.
