The prohibition of meeting traders before they reach the market and of a town-dweller selling for a desert-dweller

Sayyiduna Samurah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) forbade that the goods be met (before they reach the market) until they arrive at the markets, or that a town-dweller sell for a desert-dweller.
Ahmad and al-Tabarani (in al-Mu'jam al-Kabir) recorded it. In al-Mu'jam al-Awsat he recorded only that a town-dweller should not sell for desert-dwellers.
Al-Bazzar recorded it like Ahmad.

In one narration these words are additional, and al-Tabarani also recorded it in al-Mu'jam al-Kabir: The Prophet (peace and blessings be upon him) used to say: "Do not meet the traders until they reach the market, and do not sell for the bedouins, even if he is the brother of one of you, or his father, or his mother." The narrators of Ahmad are the narrators of the Sahih.

One of the Companions of the Prophet (peace and blessings be upon him) narrates that the Prophet (peace and blessings be upon him) said: "The traders are not to be met (outside the market), and a town-dweller shall not sell for a desert-dweller. Whoever buys a musarrah goat or she-camel (here the narrator Shu'bah mentioned only the she-camel once; the narration continues with these words:) then he has a choice between two options regarding that animal once he has milked it (either he keeps it) or, if he wishes, he returns it and returns a sa' of grain along with it." Here the narrator al-Hakam reported these words: perhaps he said that he should return a sa' of dates.
Ahmad recorded it, and its narrators are the narrators of the Sahih.

Sayyiduna Amr bin Awf (may Allah be pleased with him) relates this saying of the Prophet (peace and blessings be upon him): "Do not meet the traders (outside the market), and let no town-dweller sell for a desert-dweller."
Al-Bazzar recorded it; its chain contains a narrator, Kathir bin Abdullah bin Amr bin Awf, and he is matruk (abandoned).

Hakim bin Abi Yazid reports this statement of his father: My father narrated this hadith to me that the Prophet (peace and blessings be upon him) said: "Leave people as they are! They will obtain (provision) from one another. When one of you seeks sincere advice from his brother, he should give him sincere advice."
Ahmad recorded it; its chain contains a narrator, Ata' bin al-Sa'ib, who had become confused (ikhtilat) in his memory.

Hakim bin Abi Yazid reports from his father, from the person who heard the Prophet (peace and blessings be upon him) saying: After that, the narrator mentioned the hadith as before.
Ahmad recorded it; its chain also contains a narrator, Ata' bin al-Sa'ib.

Hakim bin Abi Yazid reports this statement of his father: The Prophet (peace and blessings be upon him) said: "Leave people as they are! They will obtain provision through one another. And when someone seeks sincere advice from his brother, he should give him sincere advice."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain also contains a narrator named Ata' bin al-Sa'ib.

Ata' bin al-Sa'ib reports from his father, this statement of his grandfather: The Prophet (peace and blessings be upon him) said: "Leave people alone! They will obtain (provision) from one another. And when your brother seeks sincere advice from you, give him sincere advice."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain also contains a narrator named Ata' bin al-Sa'ib.

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that the Prophet (peace and blessings be upon him) said: "A town-dweller shall not sell for a desert-dweller, nor buy for him."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator, Layth bin Abi Sulaym, and he is a mudallis (one who conceals defects in the chain).
