(44) باب الْبَيِّعَانِ بِالْخِيَارِ مَا لَمْ يَتَفَرَّقَا
Narrated Hakim bin Hizam:
The Prophet (ﷺ) said, "The buyer and the seller have the option of canceling or confirming the bargain unless they separate, and if they spoke the truth and made clear the defects of the goods, them they would be blessed in their bargain, and if they told lies and hid some facts, their bargain would be deprived of Allah's blessings."
