Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: In the time of the Messenger of Allah (peace and blessings be upon him) we used to buy grain. He (peace and blessings be upon him) would send word to us that "before selling it, we should move it from the place where we bought it to another place."

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said that the Messenger of Allah (peace and blessings be upon him) said: "Whoever buys grain, let him not sell it before taking possession of it." He said: We used to buy grain from the caravans by estimate, so the Messenger of Allah (peace and blessings be upon him) forbade us "to sell it before we moved it from its place."

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: I saw the people in the time of the Messenger of Allah (peace and blessings be upon him): when they bought grain by estimate, they would be beaten so that they would not sell it in that same place until they had moved it to their own quarters.

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: I bought oil in the market. When I had taken full possession of it, a man met me who offered me a good profit. I wanted to conclude the sale with him, but a man took hold of my cloak from behind. When I turned around to look, it was Sayyiduna Zayd bin Thabit (may Allah be pleased with him). He said: Do not sell it where you bought it until you have moved it to your own place, for "the Messenger of Allah (peace and blessings be upon him) forbade selling goods in the same place where they are bought until the traders move them to their own quarters."
