According to the Arab News, those on the hajj are getting a quite different message than that reported a few posts below.

With the annual pilgrimage taking place while discontent moves throughout the Islamic world, the Kingdom’s Grand Mufti Sheikh Abdul Aziz Al-Sheikh denounced all acts of terror in the strongest possible words. Delivering the sermon in the majestic Al-Namira Mosque, he said: “Islam has forbidden violence in all its forms; it has forbidden hijacking airplanes, ships and other means of transport and has forbidden all acts that would undermine security. God says the penalty for those who fight God and his Prophet and spread violence and terror is to be killed or have their hands and legs chopped off.”

He then questioned why Islam is branded by some as a religion of terror given its strong opposition to terror. “You must know of Islam’s firm stance against all these terrible crimes that are attributed to it,” he remarked.

I will take back everything I said below if this is indeed true (although it seems that some in attendance didn't appreciate the message).
