Praise be to Allaah.
If the young man who has proposed to you is pleasing in terms
of religious commitment and character, then you should accept to marry him.
You do not have to tell him about the matter of the hymen – if it is proven
that it was broken – because there is no interest to be served by telling
him, and because of the negative consequences that may result from telling
him.
If he asks you after you get married, you can pretend that
you did not know and you can use double entrendres. The hymen may be broken
by many things, such as jumping, riding a bike, heavy menstruation,
insertion of a finger, and so on. If you are forced to lie and you are
afraid that if he finds out the truth he will divorce you, it is permissible
to you to do that.
The scholars said concerning someone who fell into zina then
repented, that she does not have to tell her husband and that it is
permissible for her to lie in order to conceal herself. Undoubtedly one who
was raped and did not approach sin by her own choice, or one to whom that
happened before the age of accountability, is more deserving of being
covered.
