Narrated Hakim bin Hizam (Radi-Allahu 'anhu):
The Prophet (Sallallahu 'Alaihi Wa Sallam) said, "The buyer and the seller
have the option to cancel or to confirm the deal, as long as they have not
parted or till they part, and if they spoke the truth and told each other
the defects of the things, then blessings would be in their deal, and if
they hid something and told lies, the blessing of the deal would be lost."
