The Prophet said, "Allah said, 'I will be an opponent to three types of people on the Day of Resurrection: -1. One who makes a covenant in My Name, but proves treacherous; -2. One who sells a free person and eats his price; and -3. One who employs a laborer and takes full work from him but does not pay him for his lab our.' "

Abu 'Ali said: I heard Abu Dawud say: Sufyan said: none of you must buy in opposition to one another ; that is he says: I have a better one for ten (dirhams).

Yahya related to me from Malik that Yahya ibn Said heard Said ibn al-Musayyab say, "Keeping gold and silver out of circulation is part of working corruption in the land."

Malik said, "There is no harm in buying gold with silver or silver with gold without measuring if it is unminted or a piece of jewellery which has been made. Counted dirhams and counted dinars should not be bought without reckoning until they are known and counted. To abandon number and buy them at random would only be to speculate. That is not part of the business transactions of Muslims. As for what is weighed of unminted objects and jewellery, there is no harm in buying such things without measuring. To buy them without measuring is like buying wheat, dried dates, and such food-stuffs, which are sold without measuring, even though things like them are measured "

Malik spoke about buying a Qur'an, a sword or a signet ring which had some gold or silver work on it with dinars or dirhams. He said, "The value of the object bought with dinars, which has gold in it is looked at. If the value of the gold is up to one-third of the price, it is permitted and there is no harm in it if the sale is hand to hand and there is no deferment in it. When something is bought with silver which has silver in it, the value is looked at. If the value of the silver is one- third, it is permitted and there is no harm in it if the sale is hand to hand. That is still the way of doing things among us."

Ibn 'Umar (Allah be pleased with them) reported that the people of pre-Islamic days used to sell the meat of the slaughtered camel up to habal al-habala. And habal al-habala implies that a she-camel should give birth and then the (born one should grow young) and become pregnant. Allah's Messenger (may peace be upon him) forbade them that (this transaction).

The Prophet said, "If a slave-girl commits illegal sexual intercourse and it is proved beyond doubt, then her owner should lash her and should not blame her after the legal punishment. And then if she repeats the illegal sexual intercourse he should lash her again and should not blame her after the legal punishment, and if she commits it a third time, then he should sell her even for a hair rope."

That he was in the company of the Prophet on a journey, riding a troublesome camel belonging to `Umar. The camel used to go ahead of the Prophet, so Ibn `Umar's father would say, "O `Abdullah! No one should go ahead of the Prophet." The Prophet said to him, "Sell it to me." `Umar said to the Prophet "It is for you." So, he bought it and said, "O `Abdullah! It is for you, and you can do with it what you like."

The Prophet (saws) bought a horse from a Bedouin. The Prophet (saws) took him with him to pay him the price of his horse. The Messenger of Allah (saws) walked quickly and the Bedouin walked slowly. The people stopped the Bedouin and began to bargain with him for the horse as and they did not know that the Prophet (saws) had bought it.

The Bedouin called the Messenger of Allah (saws) saying: If you want this horse, (then buy it), otherwise I shall sell it. The Prophet (saws) stopped when he heard the call of the Bedouin, and said: Have I not bought it from you? The Bedouin said: I swear by Allah, I have not sold it to you. The Prophet (saws) said: Yes, I have bought it from you. The Bedouin began to say: Bring a witness. Khuzaymah ibn Thabit then said: I bear witness that you have bought it. The Prophet (saws) turned to Khuzaymah and said: On what (grounds) do you bear witness?

He said: By considering you trustworthy, Messenger of Allah (saws)! The Prophet (saws) made the witness of Khuzaymah equivalent to the witness of two people.

Malik related to me from Umar ibn Abd ar-Rahman ibn Dalaf al- Muzani from his father that a man from the Juhayna tribe used to buy camels before people set out for hajj and sell them at a higher price. Then he travelled quickly and used to arrive in Makka before the others who set out for hajj. He went bankrupt and his situation was put before Umar ibn al-Khattab, who said, "O People! al-Usayfi, al- Usayfi of the Juhayna, was satisfied with his deen and his trust because it was said of him that he arrived before the others on hajj. He used to incur debts which he was not careful to repay, so all of his property has been eaten up by it. Whoever has a debt against him, let him come to us tomorrow and we will divide his property between his creditors. Beware of debts! Their beginning is a worry and their end is destitution. "

The Messenger of Allah (saws) said: Gold is to be paid for with gold, raw and coined, silver with silver, raw and coined (in equal weight), wheat with wheat in equal measure, barley with barley in equal measure, dates with dates in equal measure, salt by salt with equal measure; if anyone gives more or asks more, he has dealt in usury. But there is no harm in selling gold for silver and silver (for gold), in unequal weight, payment being made on the spot. Do not sell them if they are to be paid for later. There is no harm in selling wheat for barley and barley (for wheat) in unequal measure, payment being made on the spot. If the payment is to be made later, then do not sell them.

Abu Dawud said: This tradition has also been transmitted by Sa'id b. Abi 'Arubah, Hisham al-Dastawa'i and Qatadah from Muslim b. Yasar through his chain.

Aisha told me that Barirah came to seek her help in writing for emancipation and at that time she had not paid any part of her price. `Aisha said to her, "Go to your masters and if they agree that I will pay your price (and free you) on condition that your Wala' will be for me, I will pay the money." Barirah told her masters about that, but they refused, and said, "If `Aisha wants to do a favor she could, but your Wala will be for us." Aisha informed Allah's Apostle of that and he said to her, "Buy and manumit Barirah as the Wala' will go to the manumitted."

That the Messenger of Allah (saws) said: "The dweller of the town is not to sell for the Bedouin, leave the people ; Allah provides for some of them through others."

[Abu 'Eisa said:] The Hadith of Abu Hurairah is a Hasan Sahih Hadith, and this Hadith of Jabir is a Hasan Sahih Hadith as well.

This Hadith is acted upon according to some of the people of knowledge among the Companions of the Prophet (saws) and others. They dislike the dweller of the town to sell for the Bedouin, while some of them permitted the town dweller to purchase for the Bedouin. Ash-Shafi'i said: "It is disliked for the dweller of the town to sell for the Bedouin, and if he does sell, then the sale is permissible.

Yahya related to me, that Malik said, "The generally agreed on way of doing things among us about a man buying cloth in one city, and then taking it to another city to sell as a murabaha, is that he is not reckoned to have the wage of an agent, or any allowance for ironing, folding, straightening, expenses, or the rent of a house. As for the cost of transporting the drapery, it is included in the basic price, and no share of the profit is allocated to it unless the agent tells all of that to the investor. If they agree to share the profits accordingly after knowledge of it, there is no harm in that."

Malik said, "As for bleaching, tailoring, dyeing, and such things, they are treated in the same way as drapery. The profit is reckoned in them as it is reckoned in drapery goods. So if he sells the drapery goods without clarifying the things we named as not getting profit, and if the drapery has already gone, the transport is to be reckoned, but no profit is given. If the drapery goods have not gone the transaction between them is null and void unless they make a new mutual agreement on what is to be permitted between them ."

Malik spoke about an agent who bought goods for gold or silver, and the exchange rate on the day of purchase was ten dirhams to the dinar. He took them to a city to sell murabaha, or sold them where he purchased them according to the exchange rate of the day on which he sold them. If he bought them for dirhams and he sold them for dinars, or he bought them for dinars and he sold them for dirhams, and the goods had not gone then he had a choice. If he wished, he accepted to sell the goods and if he wished, he left them. If the goods had been sold, he had the price for which the salesman bought them, and the salesman was reckoned to have the profit on what they were bought for, over what the investor gained as profit.

Malik said, "If a man sells goods worth one hundred dinars for one hundred and ten, and he hears after that they are worth ninety dinars, and the goods have gone, the seller has a choice. If he likes, he has the price of the goods on the day they were taken from him unless the price is more than the price for which he was obliged to sell them in the first place, and he does not have more than that - and it is one hundred and ten dinars. If he likes, it is counted as profit against ninety unless the price his goods reached was less than the value. He is given the choice between what his goods fetch and the capital plus the profit, which is ninety-nine dinars."

Malik said, "If someone sells goods in murabaha and he says, 'It was valued at one hundred dinars to me.' Then he hears later on, that it was worth one hundred and twenty dinars, the customer is given the choice. If he wishes, he gives the salesman the value of the goods on the day he took them, and if he wishes, he gives the price for which he bought them according to the reckoning of what profit he gives him, as far as it goes, unless that is less than the price for which he bought them, for he should not give the owner of the goods a loss from the price for which he bought them because he was satisfied with that. The owner of the goods came to seek extra, so the buyer has no argument against the salesman in that to make a reduction from the first price for which he bought it according to the list of contents."

Abdullah (b. Umar) (Allah be pleased with them) reported Allah's Messenger (may peace be upon him) having forbidden Mazabana, and it implies that one should sell the fresh fruits of his orchard (for dry fruits) or, if it is fresh dates, for dry dates with a measure, or if it is grapes for raisins or if it is corn in the field for dry corn with a measure He (the Holy Prophet) in fact forbade all such transactions. Qutaiba has narrated it with a slight variation of words.

Aisha said that Barirah came to seek her help in the writing of her emancipation. `Aisha said to her, "If you wish, I will pay your masters (your price) and the wala' will be for me." When Allah's Apostle came, she told him about it. The Prophet said to her, "Buy her (i.e. Barirah) and manumit (free) her, for the Wala is for the one who manumits." Then Allah's Apostle ascended the pulpit and said, "What about those people who stipulate conditions which are not in Allah's Laws? Whoever stipulates such conditions as are not in Allah's Laws, then those conditions are invalid even if he stipulated a hundred such conditions."

When Allah revealed the Verse: "Warn your nearest kinsmen," Allah's Apostle got up and said, "O people of Quraish (or said similar words)! Buy (i.e. save) yourselves (from the Hellfire) as I cannot save you from Allah's Punishment; O Bani `Abd Manaf! I cannot save you from Allah's Punishment, O Safiya, the Aunt of Allah's Apostle! I cannot save you from Allah's Punishment; O Fatima bint Muhammad! Ask me anything from my wealth, but I cannot save you from Allah's Punishment."
