Re: Where did the Black Stone held in Ka'bah come from?
When I said they were given "book" it didn't simply mean they had a book at home to 'recite' rather a code of life which they stuck to their abilities which is not true in case of pagans who had their own rituals/celebrations/ways etc.
Good, so you agree with my point of view that they did not practice Abrahimic 'rituals' (if there ever were any).
