Salim al-Makki (may Allah have mercy on him) says that a Bedouin narrated: In the time of the Prophet (peace and blessings be upon him) I brought a milch animal of mine (to Madinah) and came to Talhah bin Ubaydullah (may Allah be pleased with him), and I said: I have no knowledge of this market; if only you would sell it for me. So Sayyiduna Talhah (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) forbade "that a town-dweller should sell for a desert-dweller." But go to the market, and whoever wants to buy from you, consult me, so that I tell you to sell or forbid you.
