Praise be to Allah.The basic ruling on food and drink is that things are halaal, except for those which are specifically described in sharee’ah as being haraam, such as alcoholic drinks. If the drink includes any intoxicating substance, it is haraam. On this basis it may be said that beer (a drink made from barley), if it is intoxicating when drunk in large amounts, then it is not permissible to drink it. It was reported that the Prophet (peace and blessings of Allaah be upon him) said: “Every intoxicating substance is haraam.” (Narrated by al-Bukhaari, al-Ahkaam, 6637) And it was narrated that ‘Aa’ishah said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) said: ‘Every intoxicating substance is haraam, and whatever intoxicates in large amounts, a handful of it is haraam.’” (Narrated by al-Tirmidhi, al-Ashribah, 1789; classed as saheeh by al-Albaani in Saheeh Sunan al-Tirmidhi, 1521). Al-Teebi said: “ ‘a handful of it’ is an expression meaning a small amount.” And Allaah knows best.
