Allah Most High says:

"But if he is in hardship, then deferment until a time of ease. But to remit it as charity is better for you, if you only knew." (Surah al-Baqarah, 280)

One of the most important behaviors of traders is good communication with the customer. This includes welcoming the buyer with kind words and actions, being cute to them, being generous in dealing the price and well-mannered in demanding the price. A Muslim should always be beautiful and generous. Especially in buying and selling. In such cases, stubbornness and insistence even for the one coin are not rewarding. On the contrary, generosity, openness, and a little reducing the price give the result of Allah's mercy and blessing.
