Be fair and just when dealing with others; Practice honesty and integrity in our dealings with others; Do not take advantage of people; Do not engage in any form of exploitation or injustice.

The hadith narrated by Abu Hurairah states that when exchanging goods of the same type, it should be done equally. This means that if someone is trading dates for dates, wheat for wheat, barley for barley or salt for salt then they must exchange them in equal amounts. If one party gives more than the other then this is considered usury or Riba which is forbidden in Islam. This hadith teaches us to be fair and just when dealing with others and not to take advantage of them. It also encourages us to practice honesty and integrity in our dealings with others so as not to engage in any form of exploitation or injustice.
