Narrated `Abdullah bin `Umar: Allah's Apostle said, "You should not try to cancel the purchases of one another (to get a benefit thereof), and do not go ahead to meet the caravan (for buying the goods) (but wait) till it reaches the market."

Narrated `Abdullah bin `Umar: Allah's Apostle said, "Do not urge somebody to return what he has already bought (i.e. in optional sale) from another seller so as to sell him your own goods."

Narrated Abu Huraira: Allah's Apostle forbade the selling of things by a town dweller on behalf of a desert dweller; and similarly Najsh was forbidden. And one should not urge somebody to return the goods to the seller so as to sell him his own goods; nor should one demand the hand of a girl who has already been engaged to someone else; and a woman should not try to cause some other woman to be divorced in order to take her place.

Narrated Abu Huraira: 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).

Narrated Tawus: 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.' "

Narrated `Abdullah bin `Umar: Allah's Apostle forbade the selling of the goods of a desert dweller by a town person.

Narrated Abu Huraira: 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."

Narrated Anas bin Malik: We were forbidden that a town dweller should sell goods of a desert dweller.

Narrated Abu Huraira: The Prophet forbade the meeting (of caravans) on the way and the selling of goods by an inhabitant of the town on behalf of a desert dweller.

Narrated `Abdullah: Whoever buys an animal which has been kept unmilked for a long time, could return it, but has to pay a Sa of dates along with it. And the Prophet forbade meeting the owners of goods on the way away from the market.

Narrated Tawus: Ibn `Abbas said, "The Prophet forbade the meeting of caravans (on the way) and ordained that no townsman is permitted to sell things on behalf of a bedouin." I asked Ibn `Abbas, "What is the meaning of his saying, 'No townsman is permitted to sell things on behalf of a bedouin.' " He replied, "He should not work as a broker for him."

Narrated Abu Huraira: The Prophet said, "No town-dweller should sell for a bedouin. Do not practice Najsh (i.e. Do not offer a high price for a thing which you do not want to buy, in order to deceive the people). No Muslim should offer more for a thing already bought by his Muslim brother, nor should he demand the hand of a girl already engaged to another Muslim. A Muslim woman shall not try to bring about The divorce of her sister (i.e. another Muslim woman) in order to take her place herself."

Narrated Abu Huraira: 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.

Narrated Ibn `Umar: The Prophet decreed that one should not try to cancel a bargain already agreed upon between some other persons (by offering a bigger price). And a man should not ask for the hand of a girl who is already engaged to his Muslim brother, unless the first suitor gives her up, or allows him to ask for her hand.

Narrated Anas bin Malik: Allah's Apostle said, "Do not hate one another, and do not be jealous of one another, and do not desert each other, and O, Allah's worshipers! Be brothers. Lo! It is not permissible for any Muslim to desert (not talk to) his brother (Muslim) for more than three days."

Narrated Anas bin Malik: Allah's Apostle said, "Do not hate one another, nor be jealous of one another; and do not desert one another, but O Allah's worshipers! Be Brothers! And it is unlawful for a Muslim to desert his brother Muslim (and not to talk to him) for more than three nights."
