(Second chain) It is narrated from Sayyiduna Abdullah bin Umar, may Allah be pleased with them both, that the Messenger of Allah, peace and blessings be upon him, said: When two people engage in a transaction with each other, each of them has the option to cancel the deal until they separate, or one may give the option to the other and he accepts it, and then they make the sale upon that, then the deal becomes final. And if, after making the sale, they separate in such a state that neither of them has abandoned the transaction, then even so, the deal is established.
