Do not go out to meet riders to enter into transaction with them; none of you must buy in opposition to another, nor must you bid against one another; a townsman must not sell for a man from the desert; maintain fairness when trading and no one should take advantage of another person’s ignorance or lack of knowledge about something .

This hadith, narrated by Abu Huraira, emphasizes the importance of fairness in trading. It advises against going out to meet riders to enter into a transaction with them and buying or bidding against one another. It also warns against a townsman selling for someone from the desert as it could be unfair to either party. The hadith also states that if someone buys an animal with its udders tied up, they have two options; they can keep it if they are pleased with it or return it along with a sit of dates if they are displeased with it. This teaches us that fairness should be maintained when trading and no one should take advantage of another person’s ignorance or lack of knowledge about something. We should always strive for justice and fairness when dealing with others in any kind of transaction.
