Some people used to buy foodstuff at the head of the market and used to sell it on the spot. Allah's Apostle forbade them to sell it till they brought it to (their) places.

Allah's Apostle forbade the selling by Munabadha, i.e. to sell one's garment by casting it to the buyer not allowing him to examine or see it. Similarly he forbade the selling by Mulamasa. Mulamasa is to buy a garment, for example, by merely touching it, not looking at it.

I heard `Umar bin Al-Khattab saying, "I gave a horse to be ridden in Allah's Cause and the person who got it intended to sell it or neglected it. So, I wanted to buy it as I thought he would sell it cheap. I consulted the Prophet who said, "Do not buy it even if for one Dirham, because he who takes back his gift is like a dog swallowing its vomit."

The Prophet said, "He who buys foodstuff should not sell it till he has received it."

'Abdullah (b. Umar) reported that Allah's Apostle (may peace be upon him) forbade Muzabana, i. e. buying of fresh dates (on) the trees for dry dates by measure, and the buying of grapes for raisins by measure and the selling of field of corn for corn by measure.

Once I gave a horse in Allah's Cause (in charity) but that person did not take care of it. I intended to buy it, as I thought he would sell it at a low price. So, I asked the Prophet (p.b.u.h) about it. He said, "Neither buy, nor take back your alms which you have given, even if the seller were willing to sell it for one Dirham, for he who takes back his alms is like the one who swallows his own vomit."

Allah's Apostle said, "Do not go forward to meet the caravan (to buy from it on the way before it reaches the town). And do not urge buyers to cancel their purchases to sell them (your own goods) yourselves, and do not practice Najsh. A town dweller should not sell the goods for the desert dweller. Do not leave sheep unmilked for a long time, when they are on sale, and whoever buys such an animal has the option of returning it, after milking it, along with a Sa of dates or keeping it. it has been kept unmilked for a long period by the seller (to deceive others).

Allah's Apostle said, "May Allah's mercy be on him who is lenient in his buying, selling, and in demanding back his money."

We used to go ahead to meet the caravan and used to buy foodstuff from them. The Prophet forbade us to sell it till it was carried to the market.

Allah's Apostle said, "He who buys foodstuff should not sell it till he is satisfied with the measure with which he has bought it.

Aisha, (mother of the faithful believers) wanted to buy a slave girl and manumit her, but her masters said that they would sell her only on the condition that her Wala' would be for them. `Aisha told Allah's Apostle of that. He said, "What they stipulate should not hinder you from buying her, as the Wala' is for the manumitted."

Narrated Salim bin 'Abdullah from Ibn Umar: Allah's Apostle said, "Do not sell or buy fruits before their benefit was evident and do not sell fresh fruits (dates) for dried dates."

That Aisha, the mother of the Believers, intended to buy a slave girl in order to manumit her. The slave girl's master said, "We are ready to sell her to you on the condition that her Wala should be for us." Aisha mentioned that to Allah's Apostle who said, "This (condition) should not prevent you from buying her, for the Wala is for the one who manumits (the slave)."

I asked Ibn `Abbas, "What is the meaning of, 'No town dweller should sell (or buy) for a desert dweller'?" Ibn `Abbas said, "It means he should not become his broker."

I saw the people buy foodstuff randomly (i.e. blindly without measuring it) in the lifetime of Allah's Apostle and they were punished (by beating), if they tried to sell it before carrying it to their own houses.

Allah's Apostle said, "A buyer should not urge a seller to restore a purchase so as to buy it himself, and do not practice Najsh; and a town dweller should not sell goods of a desert dweller."

That the Messenger of Allah (saws) said: "When you see someone selling or buying in the Masjid then say: 'May Allah not profit your business.' And when you see someone announcing about something lost then say: 'May Allah not return it to you.'"

The Hadith of Abu Hurairah is Hasan Gharib. This is acted upon according to some of the people of knowledge. They dislike selling and buying in the Masjid. This is the view of Ahmad and Ishaq. Some of the people of knowledge permitted selling and buying in the Masjid.

Ibn `Abbas said, "Allah's Apostle said, 'Do not go to meet the caravans on the way (for buying their goods without letting them know the market price); a town dweller should not sell the goods of a desert dweller on behalf of the latter.' I asked Ibn `Abbas, 'What does he mean by not selling the goods of a desert dweller by a town dweller?' He said, 'He should not become his broker.' "

I gave a horse in Allah's Cause. The person to whom it was given, did not look after it. I intended to buy it from him, thinking that he would sell it cheap. When I asked the Prophet he said, "Don't buy it, even if he gives it to you for one Dirham, as the person who takes back what he has given in charity, is like a dog that swallows back its vomit."

Bashair b. Yasir reported on the authority of some of the Companions of Allah's Messenger (may peace be upon him) among the members of his family among whom one was Sahl b. Abu Hathma that Allah's Messenger (may peace be upon him) forbade buying of fresh dates against dry dates and that it is Riba and this is Muzabana, but he made an exemption of 'ariyya (donations) of a tree or two in which case the members of a family sell dry dates and buy fresh dates for eating them.

Yahya related to me from Malik that he had heard that a man wanted to buy food from a man in advance. The man who wanted to sell the food to him went with him to the market, and he began to show him heaps, saying, "Which one would you like me to buy for you." The buyer said to him, "Are you selling me what you do not have?" So they came to Abdullah ibn Umarand mentioned that to him. Abdallah ibn Umar said to the buyer, "Do not buy from him what he does not have." He said to the seller, "Do not sell what you do not have."

When I visited Aisha she said, "Barirah who had a written contract for her emancipation for a certain amount came to me and said, "O mother of the believers! Buy me and manumit me, as my masters will sell me." Aisha agreed to it. Barirah said, 'My masters will sell me on the condition that my Wala will go to them." Aisha said to her, 'Then I am not in need of you.' The Prophet heard of that or was told about it and so he asked Aisha, 'What is the problem of Barirah?' He said, 'Buy her and manumit her, no matter what they stipulate.' Aisha added, 'I bought and manumitted her, though her masters had stipulated that her Wala would be for them.' The Prophet said, The Wala is for the liberator, even if the other stipulated a hundred conditions."

Whoever buys a sheep which has not been milked for a long time, has the option of returning it along with one Sa of dates; and the Prophet forbade going to meet the seller on the way (as he has no knowledge of the market price and he may sell his goods at a low price).

Jabir bin 'Abdullah (Allah be pleased with them) said that the Messenger of Allah (may peace be upon him) decreed pre-emption in every joint ownership and not divided-the one-it may be a dwelling or a garden. It is not lawful for him (for the partner) to sell that until his partner gives his consent. He (the partner) is entitled to buy it when he desires and he can abandon it if he so likes. And if he (the one partner) sells it without getting the consent of the (other partner), he has the greatest right to it.

Once Bilal brought Barni (i.e. a kind of dates) to the Prophet and the Prophet asked him, "From where have you brought these?" Bilal replied, "I had some inferior type of dates and exchanged two Sas of it for one Sa of Barni dates in order to give it to the Prophet; to eat." Thereupon the Prophet said, "Beware! Beware! This is definitely Riba (usury)! This is definitely Riba (Usury)! Don't do so, but if you want to buy (a superior kind of dates) sell the inferior dates for money and then buy the superior kind of dates with that money."

The Prophet (saws) said: A townsman must not sell for a man from the desert, even if he is his brother or father.

Abu Dawud said: Anas b. Malik said: It was said: A townsman must not sell for a man from the desert. This phrase carries a broad meaning. It means that the (the townsman) must not sell anything for him or buy anything for him.

The Messenger of Allah (saws) forbade to sell grain which one buys by measurement until one receives it in full.

Hakim asked (the Prophet): Messenger of Allah, a man comes to me and wants me to sell him something which is not in my possession. Should I buy it for him from the market? He replied: Do not sell what you do not possess.

Allah's Apostle forbade (1) the meeting of the caravan (of goods) on the way, (2) and that a residing person buys for a bedouin, (3) and that a woman stipulates the divorce of the wife of the would-be husband, (4) and that a man tries to cause the cancellation of a bargain concluded by another. He also forbade An-Najsh (see Hadith 824) and that one withholds the milk in the udder of the animal so that he may deceive people on selling it.
