This hadith has been narrated on the authority of Ibn 'Umar (Allah be pleased with them) through another chain of transmitters.
Sahih Muslim Book 21, Hadith 53
← Previous Hadith Both parties in a business transaction have the right to annul it so long as they have not separated; except in transactions which have been made subject to the right of parties to annul them.

Sahih Muslim Book 21, Hadith 52 Next Hadith → When two persons enter into a transaction, each of them has the right to annul it so long as they are not separated and are together (at the place of transaction) ; or if one gives the other the right (to annul the transaction) But if one gives the other the option, the transaction is made on this condition (i. e. one has the right to annul the transaction), it becomes binding. And if they are separated after they have made the bargain and none of them annulled it, even then the transaction is binding.
