In all seriousness, I read a article once by an Arab journalist who had traveled with a small band of al Qaeda guerrilla fighters. Either in Iraq or Afghanistan. A cell of about five members, a couple Saudis, an Iraqi, an Egyptian, someone else.
The journalist said several of the fighters actually debated, when you go to Heaven you're received with seventy virgins, right? Everyone agreed. Okay, one of the guys asked, do you receive seventy virgins and that's it or are they replenished?
He said this discussion really engaged them. (Plus they talk like they're from another planet.) One would say, "Brother, as you use a virgin for your manly purposes she is, of course, no longer a virgin. Wouldn't Allah then replenish your supply? So you always have seventy virgins to choose from?" A couple of the guys agreed, several of the guys disagreed. "No my Brother, Allah supplies us with seventy virgins. That is our reward. If he replaced them that would mean we are receiving more than seventy virgins. But we are told, quite clearly, we are to receive seventy virgins, no more no less."
The Arab journalist wrote that, he came to see, that when you are with a group of people who all totally believe something, believe it without question, it becomes easy to believe it yourself.
