Practice honesty & fairness when trading goods or services; Practice charity whenever possible; Follow the teachings of Prophet Muhammad .

The Prophet Muhammad was encouraging merchants to be mindful of their business dealings and to practice charity in the process. He warned that selling often involves false oaths and idle talk which can lead to dishonesty. Therefore it is important for merchants to mix some charity into their transactions in order to ensure that they are being honest and ethical in their practices. This hadith teaches us the importance of being honest in our business dealings and how we should strive for fairness even when trading goods or services. It also encourages us to practice charity whenever possible so that we can benefit others while also benefiting ourselves.
