Keep your promises; Be honest in your dealings; Be generous towards others; Be fair when making agreements/contracts

This hadith is about a contract that was made between the Prophet Muhammad ﷺ and the people of Khaibar. The agreement was that they would give half of their yield from land and trees to Allah's Messenger ﷺ. This hadith teaches us about how important it is to keep our promises, as well as how generous Allah's Messenger ﷺ was in his dealings with others. He could have taken all of their yield, but instead he chose to be fair and only take half so that everyone could benefit from it equally. It also shows us how important it is for us to be honest in our dealings with others, even if we are not getting something out of it ourselves; this will ensure that everyone can benefit from any agreement or contract we make together.
