Is it permissible to add a condition to the marriage contract that prevents the wife from seeking khulʿ or annulment, and what are the consequences of violating this agreement?

A woman is permitted to request a khulʿ (divorce initiated by the wife) for legitimate Shar’i reasons, such as her dislike of living with her husband, or due to his bad character or religious practices. She may also request the annulment of the marriage (faskh (definition) al-nikah (definition)) due to clear harm or a defect that necessitates it. The husband’s condition stipulated at the time of the marriage contract that his wife not demand khulʿ or annulment is void, because it nullifies her rights and contradicts the essence of the contract. The contract remains valid, and the condition is nullified.
