Narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever drank alcohol in the world and did not repent, he will be deprived of (pure, that is, the pure wine of Paradise) in the Hereafter."

Abu Huraira (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings of Allah be upon him) said: "The adulterer, at the time of committing adultery, is not a believer; and the one who drinks alcohol, at the time of drinking, is not a believer; and the thief, at the time of stealing, is not a believer."

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) in another narration: "In the same way, when a thief commits a major robbery such that people raise their eyes to look at him, then at that time (i.e., while stealing) he is also not a believer."
