Abu Mas'ud al-Ansari said that God’s Messenger forbade the price paid for a dog, the hire paid to a prostitute, and the gift given to a soothsayer. (Bukhari and Muslim.)

Jabir said he heard God’s Messenger say in the year of the Conquest when he was in Mecca, "God and His Messenger have declared forbidden the sale of wine, animals which have died a natural death, swine and idols.” He was asked what he thought of the fat of animals which had died a natural death, for it was used for caulking ships, greasing skins, and making oil for lamps, and after saying that it was unlawful he added, "God curse the Jews! When He declared the fat of such animals unlawful they melted it, then sold it and enjoyed the price they received. “ (Bukhari and Muslim.)

‘Umar reported God’s Messenger as saying, "God curse the Jews! Fats were declared unlawful for them, but they melted them and sold them.” (Bukhari and Muslim.)

Anas said that Abu Taiba cupped God’s Messenger and he ordered that sa’ of dates be given him, also ordering his people to remit some of his dues.* * Abu Taiba was a client of the B. Haritha. It was the custom for a slave to hand over to his master part of what he earned. Here the Prophet (ﷺ) suggests that the masters of Abu Taiba should reduce the amount they took from him. (Bukhari and Muslim.)

‘Abdallah b. Mas'ud reported God’s Messenger as saying, “No man who acquires unlawful property and gives some of it in alms will have it accepted from him; neither will he receive a blessing for it if he con-tributes some of it; and if he leaves some of it behind him (i.e. when he dies) it will be his provision for hell. God does not obliterate an evil deed by an evil one, but He obliterates an evil deed by a good one. What is impure does not obliterate what is impure.” Ahmad transmitted it, and the same is given in Sharh as-sunna.

Wabisa b. Ma'bad reported God’s Messenger as saying, “Have you come to ask about righteousness and sin, Wabisa?” When he replied that he had, he joined his fingers and striking his breast with them said, “Ask yourself for a decision, ask your heart for a decision (saying it three times). Righteousness is that with which the soul is tranquil and the heart is tranquil, but sin is that which rouses suspicion in the soul and is perplexing in the breast, even if people give you a decision in its favour.” Ahmad and Darimi transmitted it.

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.

Abu Umama reported God’s Messenger as saying: "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.

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

Ibn 'Umar reported God's Messenger as saying, "Both parties in a business transaction have a right to annul it so long as they have not separated, except in transactions which have been made subject to the right of the parties to annul them.” The version by Bukhari and Muslim has "or one of them tells the other to exercise his right” instead of "or exercise the right.” (Bukhari and Muslim.) A version by Muslim says, "Both parties in a business transaction have a right to annul the bargain so long as they have not separated, or when their bargain has attached to it the right to annul it, for when such a condition has been made it remains valid.” A version by Tirmidhi says, "The two parties in a business transaction have a right to annul it so long as they have not separated, or exercise the right.”

Hakim b. Hizam reported God’s Messenger as saying, "Both parties in a business transaction have a right to annul it so long as they have not separated ; and if they tell the truth and make everything clear they will be blessed in their transaction, but if they conceal anything and lie the blessing on their transaction will be blotted out.” (Bukhari and Muslim.)

Ibn ‘Umar said that a man told the Prophet (ﷺ) that he was being deceived in business transactions, and he replied, "When you make a bargain say, 'There is no attempt to deceive'*.” Then the man made a habit of saying that. (Bukhari and Muslim.) * He was to say this to protect himself because he was not expert enough to detect defects in what he was buying. Some hold that one who says this has the right to cancel the transaction if any defect is discovered within three days. Some say this applied only to the man who spoke to the Prophet; others say it applies to anyone.

He reported God’s Messenger as saying, "Do not sell gold for gold unless it is like for like, and do not make one amount greater than the other; do not sell silver for silver unless it is like for like, and do not make one amount greater than the other; and do not sell for ready money something to be given later*.” A version has, "Do not sell gold for gold or silver for silver unless both are of equal weight.” (Bukhari and Muslim.) * Payment is not to be made till the goods are received.

‘Umar reported God's Messenger as saying, "Gold for gold is usury unless both hand over on the spot*; silver for silver is usury unless both hand over on the spot; wheat for wheat is usury unless both hand over on the spot; barley for barley is usury unless both hand over on the spot; dates for dates is usury unless both hand over on the spot." (Bukhari and Muslim.) *"the Arabic is ha’ waha’ meaning literally "take and take”.

Abu Sa'id and Abu Huraira told that God’s Messenger appointed a man over Khaibar and he brought him dates of a very fine quality. He asked him whether all the dates of Khaibar were like that, and he replied, “I swear by God that they are certainly not, Messenger of God. We take a sa‘ of this kind for two, and two for three." So he said, "Do not do so. Sell the lot for dirhams, then buy the very fine dates for dirhams." He said that it was the same when things were sold by weight. (Bukhari and Muslim.)

Abu Sa'id said that Bilal brought the Prophet (ﷺ) some barni* dates, and when he asked him where he had got them he replied, "I had some inferior dates, so I sold two sa's of them for a sa." He said, "Ah, the very essence of usury, the very essence of usury. Do not do so, but when you wish to buy, sell the dates in a separate transaction, then buy with what you get." (Bukhari and Muslim.) * A type of dates of the best quality, sweet and luscious, red tinged with yellow.

Abu Huraira reported God's Messenger as saying, “A time is certainly coming to mankind when only the receiver of usury will remain, and if he does not receive it some of its vapour (or alternatively, its dust) will reach him.” Ahmad, Abu Dawud, Nasa'i and Ibn Majah transmitted it.

Usama b. Zaid reported the Prophet (ﷺ) as saying, "Credit involves usury.” In a version he said, "There is no usury when payment is made on the spot.” (Bukhari and Muslim.)
