My mother is asking us sons to approve of her marriage to a man whom we do not know and who is a stranger to us. Please note that my father died and she is sixty years old. What is your advice?
If the husband has died and the woman wants to marry the guardian is obliged to arrange that marriage. It is not permissible for anyone to prevent her, because this is one of her rights. It makes no difference whether the woman is old or young, or whether she has children or not. What you have to do is ask about this man if he is good in terms of religious commitment and character.
