Ibn 'Umar said that if anyone buys a garment for ten dirhams among which is one unlawfully acquired, God most high will not accept prayer from him as long as he wears it. He then put a finger in each ear and said,“May they become deaf if the Prophet was not the one I heard say it!”Baihaqi transmitted it in Shu'ab al-iman, saying that its isnad is weak.

Jabir reported God's Messenger as saying,“God show mercy to a man who is kindly when he sells, when he buys, and when he makes a claim!”Bukhari transmitted it.

Hudhaifa reported God’s Messenger as saying,“Before your time there was a man to whom the angel came to take his spirit, and he was asked whether he had done anything good. On his replying that he did not know, he was told to consider, and then 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 God brought him into paradise.”

In a version by Muslim there is something similar on the authority of ‘Uqba b. ‘Amir and Abu Mas'ud al-Ansari. God said,“I have more right to do this than you. Forgive my servant.”(Bukhari and Muslim).

Abu Qatada reported God’s Messenger as saying,“Avoid much swearing while transacting business, for it produces a ready sale then blots out the blessing.”Muslim transmitted it.

Abu Huraira said he heard God's Messenger say,“Swearing produces a ready sale for a commodity, but blots out the blessing.”(Bukhari and Muslim.)

Abu Dharr reported the Prophet as saying,“There are three to whom God will not speak on the day of resurrection, at whom He will not look, and whom He will not declare pure, and they will have a painful punishment.”Abu Dharr said,“They are losers and disappointed. Who are they, Messenger of God?”He replied,“The one who wears a trailing robe, the one who takes account of what he gives*, and the one who produces a ready sale of a commodity by false swearing.”Muslim transmitted it. * This is the type of person who keeps reminding people of his generosity to them.

Aba Sa‘id reported God's Messenger as saying, "The truthful and trusty merchant is associated with the prophets, the upright, and the martyrs." Tirmidhi, Darimi and Daraqutni transmitted it.

Ibn Majah transmitted it on the authority of Ibn ‘Umar. Tirmidhi said this is a gharib tradition.

Qais b. Abu Gharaza said:In the time of God's Messenger we used to be called brokers, but God’s Messenger came upon us one day and called us by a better name than that, saying, "Company of merchants, unprofitable speech and swearing have a place in business dealing, so mix it with sadaqa. Abu Dawud, Tirmidhi, Nasa’i and Ibn Majah transmitted it.
