I've been reading Tariq Ali's book The Clash of Fundamentalisms, and in it he claims that the Islamic heaven is a place where infinite orgasms occur. He then suggests that the minimum duration of a heavenly orgasm is twenty-four years!! Now, of course, anyone who knows anything about Tariq Ali will realise he considers this to be a whole load of nonsense (and anyone with a sense of humour will see the ridiculous and funny side of this silly assertion regarding heavenly orgasms - the missus and I laughed so much when we read it, we ended up in stitches).
But what Tariq doesn't say - at least not in the body of his text - where this assertion comes from. Does anyone know if this is Koranic?
