Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) narrates that I heard the Noble Prophet (peace and blessings be upon him) saying:“Whoever engages in a transaction with another person, then each of them has the option (to cancel the deal) as long as they have not separated from their place, except in the case where the option has been given in the deal. And it is not permissible for anyone to separate from his companion out of fear that he will cancel the deal.”
