This is entirely incorrect. An utterance of a single "Talaq" will render the marriage void until it is renewed.

>Upon talaq, the wife is entitled to the full payment of mahr if it had not already been paid. The husband is obligated to financially support her until the end of the waiting period or the delivery of her child, if she is pregnant. In addition, she has a right to child support and any past due maintenance, which Islamic law requires to be paid regularly in the course of marriage

The prenup is hardcoded.
