Is it permissible for a virgin girl’s family to ask the person she wants to marry whether he is a virgin (meaning committed zina) or not? Also, if he if he did commit zina, is it okay for them to ask details, like number of people he slept with if he sincerely repented and is resolved to stay away from Zina? Is that relevant to why they should or shouldn’t give their daughter in marriage to him, even if he is a practicing Muslim who is dedicated to turning his life around for the sake of Allah (ta’ala)??

It is permitted for the parents to inquire about the character and “general past” of the suitor, but not about the details of possible sins. Rather, they should judge the suitor by his current character and conduct.
