Musnad Ahmad 1017:82

Mu'ammal narrated to us, Sufyan narrated to us, from 'Alqamah ibn Marthad, from Ibn Buraydah, from his father, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "I had forbidden you from three things: from visiting graves, from keeping the meat of the sacrificial animals for more than three days, and from [using] vessels. And I had forbidden you from the meat of the sacrificial animals so that those who have abundance might provide for those who do not have abundance; so eat and store [it]. And I had forbidden you from visiting graves, but Muhammad has been permitted to visit the grave of his mother. And I had forbidden you from the vessels, but the vessels do not make anything forbidden nor do they make anything lawful, and every intoxicant is forbidden."
