مسند امام احمد بن حنبل · Hadith 4566

It was narrated that 'Abdullah ibn Dinaar said: I heard 'Abdullah ibn 'Umar say: I heard the Prophet (PBUH) say: "Each party to a transaction has the option (of cancelling it) so long as they have not separated, except in the case of bay' al-khiyaar (a transaction in which the purchaser has the option of returning the goods within an agreed period).”
