Selling and buying have rulings and etiquettes in Islam that a Muslim must adhere to fulfill justice in transactions and enjoy the pleasures of this worldly life and the Hereafter. In this Hadīth, the Prophet (may Allah's peace and blessings be upon him) forbids merchants from going out and receiving those people who transport commodities from one country to another. They must not receive them before arriving and being acquainted with the prices of commodities in such a country because this might harm the seller as they might buy from him at a lower price than its known price, which would result in harming the owner of the commodity by underestimating its price. Hence, the Prophet (may Allah's peace and blessings be upon him) commanded the one who goes out to meet it and buys something thereof, and does not comply with the prohibition. So when "its master," i.e., the owner of the commodity, comes to the market, he will have the option either to effect the sale or take back his goods, for perhaps he did him injustice and wronged him regarding its price compared to its price in this country. The Hadīth encourages truthfulness and transparency and the avoidance of deceit in commercial transactions. It shows the Prophet's keenness on whatever brings goodness to his Ummah and his kindness towards them even when it comes to worldly interests..
