Do not take advantage of others in transactions; Act with fairness and justice when dealing with others; Practice honesty in dealings; Be mindful about how you spend your money.

This hadith is about usury which is a type of transaction where one party takes advantage of another by charging an excessive amount of interest. The Prophet Muhammad (PBUH) prohibited usury and stated that exchanging goods of the same kind must be done on the spot. This means that if someone wants to exchange gold for gold or wheat for wheat then it should be done immediately without any delay or extra charges. This hadith teaches us to not take advantage of others in our transactions and to always act with fairness and justice when dealing with others. It also encourages people to practice honesty in their dealings as well as being mindful about how they spend their money.
