You fail to understand my analogy as well as the verse in the Koran.
Surah 4: 43. O ye who believe! Draw not near unto prayer when ye are drunken, t
ill ye know that which ye utter, nor when you are polluted, save when journeying upon the road, till ye have bathed.
This verse can by no means be included into the process of progressive prohibition of alcohol since it does not discourage people from drinking, but from PRAYING while DRUNK. Thus, what this Koran verse objects to is not alcohol itself, but the recitation of Islamic prayer after drinking alcohol to the point of intoxication.
Perhaps you didn’t know this, but Muslims pray five times a day. Every day. Mandatory prayers. At specific times. If you get drunk, it’s going to be extremely difficult to not miss a prayer, because of how frequent they are. Say you go out and drink after work when you get home… it’s summer, maybe you’ve already prayed the afternoon prayer but the sun is still up… you’ve got 3 hours before you must pray the next prayer, or it’s late! (very bad) So if you get drunk… you’ll have to miss that prayer. And if you start drinking after that one, then you’ll miss the next. And if you drink at night, you won’t be able to get up for the morning one. So it would be extremely difficult to fit alcohol into your daily routine and keep up the prayers because they are so frequent. Therefore to maintain all your prayers you’d have to pretty much stop, or only be able to drink a little maybe at night if you were still insistent. And then it was eventually prohibited altogether, and there’s a hadith saying that a person’s prayer won’t be accepted for 40 days after drinking–not getting drunk there, but just after drinking. But it wasn’t always prohibited, and gradually became so.
Further, this same Koran verse strikingly draws parallelism between intoxication and being ritually unclean by considering them similar and ordinary. In short, 4:43 allows men to drink alcohol and feel drunk, but prohibits them from praying in that state. Therefore, 4:43 has nothing to do with progressive prohibition of strong drinks.
