Make sure you are in agreement with each other before making any kind of deal or contract .

This hadith is about transactions between two people. It teaches us that a transaction should not be considered final until both parties have the option to annul it. This means that if either party changes their mind, they can still cancel the transaction and go back to how things were before. This hadith also teaches us that we should always make sure we are in agreement with each other before making any kind of deal or contract, so that both parties are clear on what is expected of them and what will happen if one party decides to cancel the transaction.
