Every intoxicant is Khamr (alcoholic drink), and every intoxicant is prohibited. Whoever drinks Khamr in this world and dies while being addicted to it without repenting will not drink it in the Hereafter

The Prophet (may Allah's peace and blessings be upon him) clarified that whatever leads to losing control over one's mental faculties is considered intoxicant Khamr, whether it is to be drunk, eaten, inhaled, or otherwise; and whatever is intoxicant and clouds the mind is prohibited and forbidden by Allah Almighty, whether it is a small or big amount. Whoever drinks any of these intoxicants on a regular basis without repenting thereof until he dies will deserve Allah's punishment, namely being deprived of drinking it in Paradise.

1. The legal cause behind forbidding Khamr is intoxication, as whatever leads to intoxication, regardless of its type, is prohibited.
2. Allah Almighty has prohibited Khamr, given its great harms and evils.
3. Drinking Khamr in Paradise perfects the pleasure and completes the bliss.
4. He who does not abstain from drinking Khamr in this worldly life, Allah will deprive him of drinking it in Paradise because for every deed, there is a recompense that suits it.
5. Hastening to repent of sins before death is encouraged.
