it is more appropriate that it is not valid if he uses something else. As for sales (al-bay'), the formula of offer and acceptance is not a condition for it; rather, it is valid through mutual exchange (al-mu'atah). Moreover, no specific wording is determined for it; rather, it is valid with any wording that conveys the meaning. Khul' (divorce at the instance of the wife) is not binding, because it is valid to condition it upon requirements.

Section: If one enters into a marriage contract jokingly or under duress, it is valid; because the Prophet (peace and blessings of Allah be upon him) said: "There are three things in which the joke is serious and the serious is serious: divorce, marriage, and revocation (raj'ah)." Narrated by al-Tirmidhi. It is narrated from al-Hasan who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever marries playfully, or divorces playfully, or emancipates playfully, it is permitted." 'Umar said: "Four are permitted if one speaks of them: divorce, marriage, manumission, and vows." 'Ali said: "There are four in which there is no play: divorce, manumission, marriage, and vows."

This is because the ruling of the session is like the state of the contract, as evidenced by taking possession in cases where possession is a condition, and the establishment of the option (khiyar) in contracts of exchange. If they disperse before the acceptance, the offer becomes void, for its meaning is no longer present; as turning away has occurred from his side by dispersing, so it cannot be an acceptance. The same applies if they engage in something else that cuts it off, because he is also turning away from the contract by being occupied away from
