It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) forbade visiting graves, (the use of four types of) vessels, and storing the meat of sacrificial animals for more than three days. But (after some time) he said: "Indeed, I had forbidden you from visiting graves, but (now I command you) visit them, for they remind of the Hereafter. And I had forbidden you from (some) vessels, but (now I command you) use them for drinks, and avoid everything that intoxicates. And I had forbidden you from storing the meat of sacrificial animals for more than three days, but (now I say) keep the meat with you for as long as you wish."
