Salim al-Makki (may Allah have mercy on him) narrates that a Bedouin said: I came to Madinah with my milch animal and stayed with Sayyiduna Talhah bin Ubaydullah (may Allah be pleased with him). I said to him: I have no knowledge of the people of the market (and their prices), so it would be better if you sold this property for me. At this Sayyiduna Talhah bin Ubaydullah (may Allah be pleased with him) said: "Indeed, the Prophet (peace and blessings be upon him) forbade that a town-dweller should sell the goods of a Bedouin. Rather, go to the market yourself and see who will deal with you, then consult me, so that I may tell you (to make the deal) or stop you from it."
