It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that he bought a camel for thirteen dinars. The Prophet (peace and blessings be upon him) asked him, "For how much did you buy it?" He replied, "For thirteen dinars." The Prophet (peace and blessings be upon him) said, "Sell it to me for the same price you bought it, and you may ride it until you reach Madinah Munawwarah."
