It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that once the Prophet (peace and blessings be upon him) ordered me to bring a knife. I brought it, and the Prophet (peace and blessings be upon him) sent it to be sharpened. After that, handing me the knife, he said: "Bring this knife to me in the morning." I did so. The Prophet (peace and blessings be upon him) went out with his companions (may Allah be pleased with them) to the markets of Madinah, where wineskins imported from Syria were hanging. The Prophet (peace and blessings be upon him) took the knife from my hand and cut open every wineskin that came into view. After that, he gave the knife to me and ordered the companions present with him (may Allah be pleased with them) to go with me and assist me. He said to me: "Go around all the markets, and wherever you find any wineskin of wine, cut it open." So I did so, and I did not leave any wineskin in the markets without cutting it open.
