Keep your promises & agreements even if it means sacrificing your own interests for it . Be just in your dealings with others regardless of any differences you may have with them .

This hadith is about the exile of the Jewish tribes from Medina after they violated their peace treaty with Prophet Muhammad ﷺ. The Prophet ﷺ allowed Bani Quraiza to remain in their places but took away all their possessions and distributed them among the Muslims. He then granted safety to some of them who embraced Islam, and exiled all other Jews from Medina, including Bani Qainuqa', tribe of 'Abdullah bin Salam, Bani Haritha and other Jewish tribes living in Medina at that time. This hadith teaches us that it is important to keep our promises and agreements even if it means sacrificing our own interests for it. It also teaches us that we should be just in our dealings with others regardless of any differences we may have with them.
