When the Prophet’s ray of intelligence struck the dim-witted man he was with, the man got very happy, and talkative. Soon, he began unmannerly raving. This is the problem with a selflessness that comes quickly, as with wine. If the wine drinker has a deep gentleness in him, he will show that, when drunk. But if he has hidden anger and arrogance, those appear, and since most people do, wine is forbidden to everyone.
