Muhayyisa said he asked permission of God's Messenger regarding the hire of the cupper, but he forbade him. He kept on asking his permission, and at last he said, "Feed your watering-camel with it and feed your slaves with it."*Malik, Tirmidhi, Abu Dawud and Ibn Majah transmitted it.* Ibn Abd al-Barr (Isti'ab, p. 286) says Muhayyisa had a slave called Nafi' Abu Taiba who was a cupper. On p. 654 he says the name of Abu Taiba was Dinar, or Nafi', or Maisara, but God knows best. In this tradition Muhayyisa is told that he may not apply to his private use anything earned by his slave for cupping.

Abu Huraira said God's Messenger prohibited payment for a dog and the earnings of the prostitute*. * Zammara. This word is said by a number of authorities to mean a prostitute, but it can also mean a woman who plays the oboe (mizmar).It is transmitted in Sharh as-sunna.

"Do not sell, buy or teach singing-girls, and the price paid for them is unlawful. To similar effect has been sent down, 'Among men are those who purchase frivolous talk' (Al-Qur'an 31:6).Ahmad, Tirmidhi and Ibn Majah transmitted it, Tirmidhi saying that this is a gharib tradition and that ‘Ali b. Yazid the transmitter is declared to be a weak traditionist.

Do you sell milk and accept what is paid for it?” He replied that he did, and asked what harm there was in that, for he had heard God’s Messenger say, “A time is certainly coming to mankind when only the dinar and the dirham will be of use.” Ahmad transmitted it.

Nafi' said he used to fit out business expeditions to Syria and to Egypt. Having fitted out one to ‘Iraq he went to ‘A’isha, the mother of the faithful, and told her that he had been accustomed to fit out expeditions to Syria, and now he had done so to ‘Iraq. She told him not to do so, asking him what was the matter with the place with which he had traded, for she had heard God's Messenger say, “When God has appointed provision for any of you in a particular direction he should not give it up till it changes for the worse.”* Ahmad and Ibn Majah transmitted it.* Alternatives are given for this last phrase. They amount to the same thing, and so it may be understood that there was doubt as to which word was used. It reads hatta yataghayyara lahu au yatanahhara lahu. But it has been suggested that the first verb refers to lack of profit and the second to loss of capital. Cf. Mirqat, iii, 299.

Abu Bakr had a slave who brought him his earnings and Abu Bakr would eat* some of his earnings. One day he brought him something and when Abu Bakr had eaten some of it the slave asked him whether he knew what it was. Abu Bakr asked what it was, and he replied, "I acted as a soothsayer for a man in the pre-Islamic period, and not being good at it, I deceived him; but he met me and gave me that, so this is the thing of which you have eaten.” She said that Abu Bakr then put his hand in his mouth and vomited everything which was in his stomach. Bukhari transmitted it.* Here the word is used in its literal sense. Elsewhere the word is often translated by "enjoy when it is not clear that something is actually eaten.”

Abu Bakr reported God’s Messenger as saying, “Nobody which has been nourished with what is unlawful will enter paradise.” Baihaqi transmitted it in Shu'ab al-iman.

Zaid b. Aslam said that 'Umar b. al-Khattab drank some milk which pleased him and asked the one who had given him the drink where he had got that milk from. He informed him that he had gone down to a watering-place which he named where there were some of the camels of the sadaqa. The people who were watering the camels had drawn some milk for him which he had put in his milk-skin, and that was what he had given him. ‘Umar then put his hand in his mouth and vomited it. Baihaqi transmitted it in Shu'ab al-iman.

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.

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 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.
