Sahih al-Bukhari Book 73, Hadith 30
`Abdullah bin `Umar said, "Allah's Messenger (ﷺ) said, "Eat of the meat of sacrifices (of `Id al Adha) for
three days." When `Abdullah departed from Mina, he used to eat (bread with) oil, lest he should eat of
the meat of Hadi (which is regarded as unlawful after the three days of the `Id).
(in continuation of above). Then I witnessed (the 'Its) with `Ali bin Abi Talib, and he too offered the `Id prayer before the sermon and then delivered the sermon before the people and said, "Allah's Messenger (ﷺ) has forbidden you to eat the meat of your sacrifices for more than three days."
Allah's Messenger (ﷺ) said, "Whoever drinks alcoholic drinks in the world and does not repent (before dying), will be deprived of it in the Hereafter."
