Musnad Abu Ya'la al-Mawsili 128:23

Abu Khaythama narrated to us, Ya'qub ibn Ibrahim narrated to us, my father narrated to us, from Ibn Ishaq. Yahya ibn al-Harith al-Jabir narrated to me, from 'Abd al-Warith, the freed slave of Anas, and 'Amr ibn 'Amir, from Anas, who said: The Messenger of Allah (peace and blessings of Allah be upon him) forbade the visiting of graves, and the meat of the sacrificial animals after three [days], and [drinking] nabidh in gourds, green glazed jars, and pitch-coated vessels. He said: Then the Messenger of Allah (peace and blessings of Allah be upon him) said after three [days]: "I had forbidden you from three things, then it appeared to me regarding them: I forbade you from visiting graves, then it appeared to me that it softens the heart, brings tears to the eyes, and reminds one of the Hereafter, so visit them, but do not say anything forbidden (hajran). And I forbade you from the meat of the sacrificial animals, that you eat it beyond three nights, then it appeared to me that people keep their provisions, entertain their guests, and save for those who are absent, so keep [it] as much as you wish. And I forbade you from nabidh in these vessels, so drink in whatever you wish, but do not drink anything intoxicating. Whoever wishes, let him tie his waterskin, [or else he will be] upon sin."
