The riders (carrying merchandise) should not be met in the way, and townsman should not sell for a man of the desert. The narrator reported. I said to Ibn 'Abbas: What do these words really imply- The townsman for the man of the desert? He said: That he should work as a broker on his behalf.

The townsman should not sell for a man from the desert, leave the people alone, Allah will give them provision from one another. Yahya reported it with a slight change of words.
