In Islam, intoxicants are considered forbidden even in small quantity. The consumption of alcohol and other intoxicants is strictly prohibited in Islam as it can cloud a person's judgment, lead to inappropriate behavior, and harm one's health. This prohibition is based on various verses of the Qur'an and teachings of the Prophet Muhammad (peace be upon him) that emphasize the harmful effects of intoxicants and the importance of maintaining a clear and sober mind. Therefore, Muslims are expected to completely abstain from consuming any intoxicating substances.
