Herr Hitler was a well-read man. He read the koran. He says so, in Mein Kampf. Guess he was impressed by the 'pigs and monkeys' verse...and how the rocks and stones would say 'there is a Jew hiding behind me, come and kill him...'
The Fuehrer promised the mufti, Arafat's Uncle, that no Jew would be allowed to leave germany alive. Made the mufti very happy.

The article appeared in the Observer - your information is correct.
I read "Mein Kampf" but never noticed the influence of the Mufti...but I did see it as pure evil.
