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.”
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.
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.”
