Agree on terms before any exchange takes place; Offer something of value when borrowing money; Pay back loans in due time; Be honest and responsible with transactions .

This hadith is about the Prophet Muhammad borrowing grain from a Jew and pledging his iron coat-of-mail as collateral. This shows us that it is permissible to borrow money, but one must be sure to pay it back in due time. It also teaches us that when we borrow money, we should offer something of value in return as security for the loan. The Prophet Muhammad was willing to give up something valuable of his own in order to secure the loan he was taking out, showing us that we should be willing to do the same if necessary. We can also learn from this hadith that it is important for both parties involved in a transaction to agree on terms before any exchange takes place so there are no misunderstandings later on.
