Like pass on the subscription information, dude. I don't think it is that simple. There are four different orthodox legal schools in Sunni Islam, and each has its own interpretation of the prohibition. My impression is that he is generally reliable, but I haven't researched the matter further. Incidentally, I gather there is an exception for date beer that has fermented no more than three days.
Rules are rules and actual behaviors and practices are often something else.
It depends in part on what country one lives in and what sect of Islam one follows. Another example of Qur'anic rule vs. actual practice is an injunction against art depicting living beings in art. Last night I have found an interesting reference. They're pretty strict there now, but 400 years ago could well have behaved differently. As far as i know, the Indonesians learned to make beer from the Dutch who colonized the region for about 300-350 years.
