Practice fairness in all aspects of life so that everyone can benefit from it equally.

The Prophet Muhammad (PBUH) taught us to be fair in our dealings and transactions. He prohibited the sale of a heap of grain for another heap or for one with known measure. This means that we should not exchange goods without considering their value and quality. We should also not take advantage of someone else's ignorance by selling them something that is worth less than what they are paying for it. Instead, we should always strive to be honest in our dealings and ensure that both parties involved are getting an equal benefit from the transaction. This hadith teaches us to practice fairness in all aspects of life so that everyone can benefit from it equally.
