Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates: In the blessed era of the Prophet Muhammad (peace and blessings be upon him), a Jew brought barley and dates loaded on twenty-three camels. He set the price of one mudd higher than the mudd of the Prophet (peace and blessings be upon him). In those days, people had no other means of obtaining grain except this. Before this, they had suffered from hunger. During that time, they could not get any grain. They came to the Prophet (peace and blessings be upon him) and complained to him that the price had increased. The Prophet (peace and blessings be upon him) ascended the pulpit. He praised and glorified Allah, then said: I will never present myself before Allah in such a state that I have given someone’s wealth to another against his will. Buying and selling is done with mutual consent, however, there are some things in your transactions regarding which I want to advise you: do not bear malice against one another. Do not bid against each other. Do not be envious of one another, and no one should bid over his brother’s bid, and a townsman should never sell (anything) for a villager. Buying and selling is done with mutual consent. You are Allah’s servants and should live as brothers.
