Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: A consignment of oil came from Syria, and I bought several camel-loads of it and completed the purchase. Then a man came to me and offered me a good profit. I stretched out my hand to make the deal with him, when someone behind me took hold of my hand. I looked and it was Zayd bin Thabit (may Allah be pleased with him). He said: "Do not sell it until you have moved it to your lodging, for the Messenger of Allah (peace and blessings be upon him) commanded exactly that."
