AbuMajidah said: I cut the ear of a boy, or he cut my ear (the narrator is doubtful). AbuBakr then came to us to perform hajj and we got together with him. But he referred us to Umar ibn al-Khattab. Umar (ibn al-Khattab) said: This reached the extent of retaliation. Call a cupper to me so that he may retaliate. When the cupper was called, he (Umar) said: I heard the Messenger of Allah (ﷺ) say: I gave a boy to my maternal aunt, and I hope that she will be blessed in respect of him. I said to her: Do not entrust him to a supper, nor to a goldsmith, nor to a butcher. Abu Dawud said: This tradition has also been transmitted by 'Abd al-A'la from Ibn Ishaq who said: Abu Majidah is a man of Banu Sahm narrating from 'Umar b. al-Khattab.

Abu Majidah quoted 'Umar b. al-Khattab as saying: I heard the Prophet (ﷺ) say ... narrating the tradition to the same effect.

Narrated Ibn 'Umar: The Prophet (ﷺ) as saying: If anyone buys a slave who possesses property. his property belongs to the seller unless buyer makes a provision and if anyone buys palm-trees after they have been fecundated, the fruit belongs to the seller unless the buyer make a provision.

This tradition has also been narrated by 'Umar from the Messenger of Allah (ﷺ) through a different chain of narrators. It mentions only the sale of the slave. It has also been transmitted by Nafi' on the authority of Ibn 'Umar from the Prophet (ﷺ) indicating only the sale of palm-trees. Abu Dawud said: Al-Zuhri and Nafi' differed among themselves in four traditions. This is one of them.

Narrated 'Abdullah bin 'Umar: The Messenger of Allah (ﷺ) as saying: None of you must buy in opposition to one another ; and do not go out to meet the merchandise, (but one must wait) till it is brought down to the market.

Abu Hurairah said: Do not go our to meet what is being brought (to market for sale). If anyone does so and buys some of it, the owner of merchandise has a choice (of canceling the deal) when it comes to the market. 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).

Narrated Abu Hurairah: The Prophet (ﷺ) forbade to bid against one another.

Narrated Anas ibn Malik: The Prophet (ﷺ) 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.

Narrated Salim al-Makki: That a bedouin told him that he brought a milch she-camel in the time of the Messenger of Allah (ﷺ). He alighted with Talhah ibn Ubaydullah (and wanted to sell his milch animal to him). He said: The Prophet (ﷺ) forbade a townsman to sell for a man from the desert. But go to the market and see who buys from you. consult me thereafter, and then I shall ask you (to sell) or forbid you.

Narrated Jabir: The Messenger of Allah (ﷺ) as saying: A townsman must not sell for a man from the desert ; and leave people alone, Allah will give them provision from one another.

Narrated Abu Hurairah: The Messenger of Allah (ﷺ) as saying: Do not go out to meet riders to conduct business with them ; none of you must buy in opposition to one another; and do not tie up the udders of camels and sheep, for he who buys them after that has been done has two courses open to him after milking them: he may keep them if he is pleased with them, or he may return them along with a sa' of dates is he is displeased with them.

Narrated Abu Hurairah: The Prophet (ﷺ) as saying: If anyone buys sheep whose udders have been tied up, he has option for three days: he may return it if he desires with a sa' of any grain, not (necessarily) wheat.

Narrated Abu Hurairah: The Messenger of Allah (ﷺ) as saying: If anyone buys sheep or goat whose udders have been tied up and he milked it, he may keep it if he is pleased with it, or he may return it if he is displeased with it. There is one sa' of dates (which he must give to the seller) for milking it.

Narrated Ma'mar b. Abi Ma'mar, one of the children of 'Adi b. Ka'b: The Messenger of Allah (ﷺ) as saying: No one withholds goods till their price rises but a sinner. I said to Sa'id (b. al-Musayyab): You withhold goods till their price rises. He said: Ma'mar used to withhold goods till their price rose. Abu Dawud said: I asked Ahmad (b. Hanbal): What is hoarding (hukrah) ? He replied: That on which people live. Abu Dawud said: Al-Auza'i said: A muhtakir (one who hoards) is one who withholds supply of goods in the market.

Qatadah said: Hoarding does not apply to dried dates. Ibn al-Muthanna said that he (Yahya b. Fayyad) reported on the authority of al-Hasan. We (Ibn al-Muthanna) said to him (Yahya): Do not say: "on the authority of al-Hasan." Abu Dawud said: This tradition according to us is false. Abu Dawud said: Sa'id b. al-Musayyab used to hoard kernel, fodder, and seeds. Abu Dawud said: I heard Ahmad b. Yunus say: I asked Sufyan about hoarding fodder. He replied: They (the people in the past) disapproved of hoarding. I asked Abu Bakr b. 'Ayyash (about it). He replied: Hoard it.

Narrated 'Alqamah b. 'Abdullah: On the authority of his father, who said: The Messenger of Allah (ﷺ) forbade to break the coins of the Muslims current among them except for some defect.
