What is the ruling on the marriage of a Muslim woman to a young man who feigned Islam, then it became clear that he was Christian after the marriage contract?

What transpired between the questioner and the non-Muslim young man is considered a void contract by the consensus of Muslims, due to the Almighty's saying: "And do not marry polytheistic women until they believe." Therefore, it is not permissible to complete the marriage, and there is no consideration for the similarity of customs and temperaments as long as the young man remains in his disbelief. If he embraces Islam and wishes to marry, a new contract is necessary.
