Volume 3, Book 34, Number 293:
Narrated Hakim bin Hizam:
Allah’s Apostle said, “The seller and the buyer have the right to keep or return goods as long as
they have not parted or till they part; and if both the parties spoke the truth and described the defects
and qualities (of the goods), then they would be blessed in their transaction, and if they told lies or
hid something, then the blessings of their transaction would be lost.”
