The Prophet (ﷺ) said, "Both the buyer and the seller have the option of canceling or confirming the
bargain unless they separate." The sub-narrator, Hammam said, "I found this in my book: 'Both the
buyer and the seller give the option of either confirming or canceling the bargain three times, and if
they speak the truth and mention the defects, then their bargain will be blessed, and if they tell lies and
conceal the defects, they might gain some financial gain but they will deprive their sale of (Allah's)
blessings."
