Ibn Buraydah narrates from his father (Sayyiduna Buraydah, may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "I forbade you from three things, and now I command you regarding them: I forbade you from visiting graves, so now visit them, for in visiting them there is a reminder. I forbade you, regarding drinks, from drinking in leather vessels, so now drink in every vessel, but do not drink anything intoxicating. And I forbade you from eating the meat of sacrifices after three days, so now eat it and benefit from it in your journeys."
