Renting an Item to Who Sold It Is It Different from Bay Al-Wafa Contract?

Bay' al-wafa' is a contract whereby the owner of an estate (house or land) sells it, with a condition that he will have it back once he returns its price to the buyer (See Articles 118 and 396-403 of Majallat al-Ahkam al-Adliyah). In other words, he who needs cash sells his estate in cash, with the condition that whenever he returns the cash to the buyer, the latter returns to him his estate. Thus, it is a sale contract with an attached condition of abrogation, the seller returns the cash and the buyer returns the estate
