I say, and with God's success: This image has become widespread in history, and it is known in the books of jurisprudence as the sale of fulfillment. The jurists have differed on it with seven opinions, the most famous of which is that it is, on one hand, a valid sale, on another hand, an invalid sale, and on another hand, a pledge. Thus, it is valid in this comprehensive form. It has been mentioned in the Journal of Judicial Rules and was permitted, but the contract is not binding due to the existence of invalidity. The benefit is valid due to the existence of validity, and the return of the house is required due to the existence of the pledge. If it is known among the people, it is permissible to deal with it; otherwise, it is preferable to avoid it for fear of falling into usury, as in the case of a loan that involves a pledge. And God knows best.
