Narrated Hakim bin Hizam:
The Prophet said, “The buyer and the seller have the option of cancelling or confirming the bar –
gain 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.”
