The Prohibition: Al-Tirmidhi #580, Narrated AbudDarda' ...don't drink wine for it is the key to every evil.
Abu Dawood, Narrated Umar ibn al-Khattab "When the prohibition of wine (was yet to be) declared, Umar said: O Allah, give us a satisfactory explanation about wine. So the following verse of Surat al-Baqarah revealed; "They ask thee concerning wine and gambling. Say: In them is great sin...." Umar was then called and it was recited to him. He said: O Allah, give us a satisfactory explanation about wine.
Then the following verse of Surat an-Nisa' was revealed: "O ye who believe! approach not prayers with a mind befogged...."
Thereafter the herald of the Apostle of Allah would call when the (congregational) prayer was performed: Beware, one who is drunk should not come to prayer.
Umar was again called and it was recited to him. He said: O Allah, give us a satisfactory explanation about wine. This verse was revealed: "Will ye not then abstain?" Umar said: We abstained. The Noble Qur'an - al-Baqarah 2:219 They ask you (O Muhammad ) concerning alcoholic drink and gambling. Say: "In them is a great sin, and (some) benefit for men, but the sin of them is greater than their benefit." And they ask you what they ought to spend. Say: "That which is beyond your needs." Thus Allâh makes clear to you His Laws in order that you may give thought.
Selling and Buying: Al-Tirmidhi #2776 Narrated Anas ibn Malik "Allah's Messenger cursed ten people in connection with wine: the wine-presser, the one who has it pressed, the one who drinks it, the one who conveys it, the one to whom it is conveyed, the one who serves it, the one who sells it, the one who benefits from the price paid for it, the one who buys it, and the one for whom it is bought." Tirmidhi and Ibn Majah transmitted it.
Dying when Addicted: Muslim #4963, Narrated Abdullah ibn Umar "Allah's Messenger said: Every intoxicant is Khamr and every intoxicant is forbidden. He who drinks wine in this world and dies while he is addicted to it, not having repented, will not be given a drink in the Hereafter."
