The Book of Prayers (Kitab Al-Salat)
Muslim :: Book 4 : Hadith 2131
Ibn Buraida reported on the authority of his father that the Messenger of Allah (may peace be upon him) said: I forbade you to visit graves, but you may now visit them; I forbade you to eat the flesh of sacrificial animals after three days, but you way now keep it as along as you feel inclined; and I forbade you nabidh except in a water-skin, you may drink it from all kinds of water-skins, but you must not drink anything intoxicating.
