Be honest in all transactions; Be fair in dealings with others; Do no harm or injustice; Agree on terms before making any transaction

This hadith is about the permissibility of purchasing property from non-Muslims. The Prophet Muhammad ﷺ approved of Mu'adh's purchase of a Jewish man's property, even though the heir was Muslim. This hadith teaches us that it is permissible to buy and sell with non-Muslims, as long as both parties are in agreement and no harm or injustice is done to either party. It also teaches us that Muslims should be fair in their dealings with others, regardless of their faith or background. Furthermore, this hadith encourages Muslims to be honest in all their transactions and not take advantage of those who may not have the same knowledge or understanding as them when it comes to business matters.
