question #3 Sahih al-Bukhari 2112, Book 34, Hadith 65 : What happens to a transaction if the buyer and seller separate without rejecting the bargain?

Allah’s Messenger (ﷺ) said, “Both the buyer and the seller have the option of canceling or confirming the
bargain, as long as they are still together; and unless they separate or one of them gives the other the
option of keeping or returning the things and a decision is concluded then, in which case the bargain is considered final. If they separate after the bargain and none of them has rejected it, then the bargain is rendered final.”
