Abdullah bin Tawus (may Allah have mercy on him) narrates from his father that he said: The Messenger of Allah (peace and blessings be upon him) gave a man the option after the sale. The man said to him: May Allah prolong your life, from which people are you? The Messenger of Allah (peace and blessings be upon him) said: "A man from Quraysh." He (Ibn Tawus) said: My father used to swear that the option is only after the sale.
