(44) Chapter. Both the buyer and the seller have the option to cancel or confirm the bargain, unless they separate.

Narrated Hakim bin Hizam: The Prophet 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."

Narrated `Abdullah bin `Umar: Allah's Apostle said, "Both the buyer and the seller have the option of canceling or confirming a bargain unless they separate, or the sale is optional." (See Hadith No.320).
