Chapter: Is it permissible for a person from the town to sell the goods of a desert dweller

I have given a pledge of allegiance to Allah's Messenger (ﷺ) for to testify that None has the right to be worshipped but Allah, and Muhammad is His Apostle, to offer prayers perfectly, to pay Zakat, to listen to and obey (Allah's and His Prophet's orders), and to give good advice to every Muslim.

Ibn `Abbas said, "Allah's Messenger (ﷺ) 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.' "
