Muhammad (peace be upon him) was always fair and honest in his dealings with other people even before his prophethood. When he attained the age of maturity he became a trader and went on expeditions to the Middle East countries. He traded with other people's money with great prudence and made large profits. The people of Makkah were very much impressed by his trading skill and fair dealing. Gradually he became well-known and the people trusted him. It was his honesty and fair dealing in business that impressed Khadijah (may Allah be pleased with her), who first entrusted her enterprise to him and later married him. All the people who had done business dealings with him before his prophethood had always praised his honesty and fair dealing in trade. He was not only fair in business dealings with other people but also encouraged his companions to be so. An-Nauman bin Bashir (may Allah be pleased with him) reported Allah's Messenger (peace be upon him) as saying, "What is lawful is clear and what is unlawful is clear, but between them are certain doubtful things which many people do not recognize. He who guards against doubtful things keeps his religion and his honor blameless, but he who falls into doubtful things falls into what is unlawful, just as a shepherd who pastures his animals round a national reserve will soon pasture them in it. Every king has a reserve and Allah's reserve is the things He has declared unlawful." (Bukhari and Muslim). And Abdullah ibn Masud (may Allah be pleased with him) reported Allah's Messenger (peace be upon him) as saying, "Trying to earn a lawful livelihood is an obligatory duty in addition to the duties which are obligatory." Rafi ibn Khadij (may Allah be pleased with him) said that Allah's Messenger (peace be upon him) was asked what type of earning was best and he replied, "A man's work with his hands and every business transaction which is approved." (Ahmad). Jabir (may Allah be pleased with him) reported Allah's Messenger (peace be upon him) as saying, "Allah shows mercy to a man who is kindly when he sells, when he buys and when he makes a claim." (Bukhari).

Abu Saeed (may Allah be pleased with him) reported Allah's Messenger (peace be upon him) as saying, "The truthful and trustworthy merchant is associated with the Prophets, the upright and the martyrs." (Tirmizi, Darimi and Ibn Majah). Hudhaifa (may Allah be pleased with him) reported Allah's Messenger (peace be upon him) as saying, "Before your time there was a man who, when the angel came to take his soul, was asked whether he had done anything good and he replied that he did not know. He was told to consider, and then he said that the only thing he knew was that he used to have business dealings with people in the world and would demand his rights from them, giving the rich time to pay and letting the poor off. So Allah brought him into Paradise." (Bukhari and Muslim).

Muhammad (peace be upon him) clearly warned those who did not do fair dealings. Abdullah ibn Masud (may Allah be pleased with him) reported Allah's Messenger (peace be upon him) as saying, "No man who acquires unlawful property and gives some of it in charity will have it accepted from him; neither will he receive a blessing for it; and if he leaves some of it behind him it will be his provision for hell." (Ahmad). And Abu Bakr (may Allah be pleased with him) reported Allah's Messenger (peace be upon him) as saying, "Nobody who has been nourished with what is unlawful will enter Paradise." Many incidents can be quoted from the life of Muhammad (peace be upon him) to show how just and fair he was in his business dealings with other people. There was a famous trader, named Saib, in Arabia, who embraced Islam and came to see Muhammad (peace be upon him). The Muslims introduced him with some commendatory words to the Prophet (peace be upon him). The Prophet (peace be upon him) said, "I know him better than you." Saib (may Allah be pleased with him) said, "My parents be sacrificed, he was my partner and always kept business dealings fair and clean.') Once Muhammad (peace be upon him) borrowed some dates from a man who came back a few days later and demanded payment of his debt. Muhammad (peace be upon him) asked one of the Ansar to pay off his debt. The Ansari paid back his dates but they were not of the same quality as had been given by him to the Prophet (peace be upon him). He refused to accept them. The Ansari told him that he was refusing to accept the dates given by the Prophet (peace be upon him). He replied, "Yes, if the Messenger of Allah will not do justice, from whom shall we expect it?" When the Prophet (peace be upon him) heard this, tears came into his eyes and he said, "It is quite true."

Once Muhammad (peace be upon him) borrowed some money from a Beduin. He came back and spoke very harshly to the Prophet (peace be upon him). The companions rebuked him for his arrogance and said, "Do you know who you are talking to?" He replied that he was demanding his due. The Prophet (peace be upon him) said to his companions, "You ought to support him for he has right to speak." Then he asked his companions to pay off his debt and give some more. In a battle, Jabir ibn Abdullah Al-Ansari (may Allah be pleased with him) was accompanying the Prophet (peace be upon him). His camel was slow, and after the journey, having been completely worn out, it became very slow. The Prophet (peace be upon him) bought his camel and then gave it back to him along with the money and said "Both are yours." Once he borrowed a camel from someone and returned a better one. Then he said, "The best people are those who pay off their debts joyfully."

Once a Bedouin was selling the meat of a camel. Muhammad (peace be upon him) thought that there were some dry dates at home, so he bought some meat for one Wasq of dates. When he came home he found there were no dates. He came out of the house and told the Bedouin that he had bought meat in exchange for dates but he had no dates. The Bedouin began to shout that he had been tricked. The people advised him that the Messenger of Allah (peace be upon him) would not do unfair dealing with anyone. The Prophet said (peace be upon him), "Leave him; he has the right to protest." This continued for some time and each time the Prophet (peace be upon him) said, "He has the right to protest." Then the Prophet (peace be upon him) sent him to an Ansari woman and asked him to get his dates for the meat from her. When he returned with the dates, the Prophet (peace be upon him) was sitting with his companions. He was very much impressed by the gentleness, forgiveness and fair dealings of the Prophet (peace be upon him). Seeing the Prophet (peace be upon him) he said, "Muhammad! May Allah give you a better reward; you have paid the full price with goodness."

Once, a small caravan was staying outside Madinah. They had a red camel. By chance, Muhammad (peace be upon him) passed that way and asked the price of the camel. The people told him the price, which he accepted without argument. Muhammad (peace be upon him) caught the bridle of the camel and walked towards the city. Afterwards the people regretted that they had given the camel without any acquaintance. There was a woman in the caravan who said, "Be comforted. We have not seen a man with a brighter face than his." In other words, such a man would not deceive. When night fell, Muhammad (peace be upon him) sent food for them and dates for the price of the camel. Muhammad (peace be upon him) needed some armaments in the battle of Hunain. He asked Safwan, an unbeliever, to lend him some chain armor. He replied, "Muhammad! You intend to usurp something?" The Prophet (peace be upon him) said, "No, I am taking it on loan. If some is lost, I will pay the proper compensation." He gave forty sets of chain armor on loan. After the battle, some of the chain armor was found to be missing. The Prophet (peace be upon him) told Safwan that some of his armor was lost, and he could accept compensation for them. Safwan replied, "O Messenger of Allah! The condition of my heart is not as it was before. In other words, I have embraced Islam; now I don't need compensation."
