[3856] 45 - (...) 'Abdullâh bin 'Umar said: "The Messenger of Allâh ﷺ said: 'When two parties enter into a transaction, each of them has the option of (canceling) the sale, so long as they have not parted, but if they chose to agree on a deal, then it becomes binding.'" Ibn Abî 'Umar added in his report: "Nâfi' said: 'If he entered into a transaction with a man and intended not to let him off, he would get up and walk away for a while, then come back to him.'"
