Alcohol in Malaysia
Alcohol is generally prohibited for Muslim consumers in the country as Malaysia's sharia law forbids Muslim from drinking and selling alcohol to them. Alcohol is mostly banned for Muslims in the states of Kelantan and Terengganu. The legal age drinking for Malaysia is 21 years old and above, which was changed from the previous legal drinking age of 18, as of 1 December 2017. The legal limit for alcohol while driving in Malaysia is 80 milligrams per decilitre or 100 millilitres. Any vendors, restaurants and retailers need a license to serve or sell tap/draft beers, liquor and spirits in the country, but bottled and canned beers are exempted from such license requirements which is why it is common to find many vendors and coffee houses continue to serving alcohol in their premises without any license throughout the country. Malaysia also impose a nationwide regulations for vendors to place their alcoholic drinks into separate refrigerators or storage places, although this was opposed by certain vendors in the state of Penang. The high tax on alcohol has led to the increase price of alcoholic drinks in Malaysia, this has contributed to alcohol-related harm as many indigenous in the interior turn to unsafe alcohol that being smuggled from neighbouring countries.
Khamr
As far as the prohibition of alcohol in the Koran is concerned alcohol was prohibited after an incident which is recorded in the Sunni hadith literature in a hadith found in "Jami a Tirmidhi" where some companions of the Islamic prophet, Muhammad, were guests at a meal and drank wine and verses of the Koran were revealed. The narrative is found in "Chapters of Tafsir Vol.5 Book 44 Hadith No. 3026."
""Narrated Abu 'Abdur-Rahman As-Sulami: that 'Ali bin Abi Talib said: "'Abdur-Rahman bin 'Awf prepared some food for which he invited us, and he gave us some wine to drink. The wine began to affect us when it was time for Salat. So they encouraged me (to lead) and I recited: 'Say: O you disbelievers! I do not worship what you worship, and we worship what we worship' - so Allah, Most High, revealed: O you who believe! Do not approach Salat when you are in a drunken state until you know what you are saying (4:43).""
