question #1 Sahih al-Bukhari 2274, Book 37, Hadith 14 : What is the significance of the prohibition against meeting caravans on the way in Islamic trade practices?

Ibn `Abbas said, “The Prophet (ﷺ) 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.”
