and he was riding it before taking possession of it from Umar, may Allah be pleased with him. This was a disposal by way of an uncompensated gift. Hence the hadith states: “He must not sell it until he takes possession of it.” (1) It is well known that a sale is an exchange for consideration. Since the Prophet ﷺ mentioned sale alone, this indicates that whatever resembles it—such as rent and a compensatory gift, meaning a gift given in return for compensation—comes under the same ruling. But whatever does not share the same effective cause and is not intended as an exchange for consideration, but is intended for the sake of Allah in the case of charity, or to express affection and goodwill in the case of a present or gift, does not share the same ruling. Drawing an analogy between gifts and presents, on the one hand, and sale, on the other, is an analogy with a relevant distinction.
His statement, “His disposal of it is not valid until he takes possession of it,” is the third ruling. The apparent meaning of his words applies even when the disposal is made with the seller—that is, even if it is made with the seller himself.
For example: I purchased one hundred sāʿ of goods from this man, and they are presently in my possession. I then sell them back to him for their original price or for more. Is this valid?
