Be honest & fair when dealing with others financially

In this hadith, the Prophet Muhammad is warning against the practice of usury or riba. This is a type of financial transaction where one person takes advantage of another by charging them an unfair amount for goods or services. In this case, Bilal was trying to buy some dates but was being charged too much money for them. The Prophet Muhammad then warned him not to take part in such a transaction as it would be considered wrong and unethical. He wanted people to be fair and honest when dealing with each other financially and not take advantage of others in any way. This hadith teaches us that we should always strive to be fair and just when dealing with others financially and never try to take advantage of someone else's situation for our own gain.
