It is narrated from Sayyiduna Hakim bin Hizam (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: The buyer and the seller have the option (to cancel the transaction) as long as they have not separated. If both act truthfully in the transaction and make everything clear, they will be blessed in their trade; but if they lie and conceal (defects, etc.), the blessing will be taken away from their trade.

It is narrated from Sayyiduna Abu Barzah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: The two persons involved in a transaction have the option (to cancel the sale) as long as they do not separate.

Narrated by Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: The two persons involved in a transaction have the option (to cancel the deal) until they separate, unless it is a trade with the option (already specified), or one says to the other: You have the option.

(Second chain) It is narrated from Sayyiduna Abdullah bin Umar, may Allah be pleased with them both, that the Messenger of Allah, peace and blessings be upon him, said: When two people engage in a transaction with each other, each of them has the option to cancel the deal until they separate, or one may give the option to the other and he accepts it, and then they make the sale upon that, then the deal becomes final. And if, after making the sale, they separate in such a state that neither of them has abandoned the transaction, then even so, the deal is established.

Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) narrates that the Noble Prophet (peace and blessings be upon him) said: The seller and the buyer both have the option to cancel the transaction before they separate, unless it is an option-based transaction, and it is not permissible for a person to separate out of fear that the transaction will be cancelled.

Narrated by Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Both parties involved in a sale have the option to cancel the transaction before they separate, or if their sale is based on choice.

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: The two men engaged in trade should separate with mutual consent.
