The Danish caricatures of the Prophet Mohammad were widely condemned in the Muslim world and led to violent protests, attacks on embassies and even deaths. Even in recent days, they have continued to stir more protest (in Pakistan) and create security problems (in Afghanistan). They have set off a kind of “clash of civilisations” with a Muslim side denouncing them as blasphemy and a western side defending them as freedom of speech. The whole dispute has been extremely polarising.

Now one of the most popular preachers in the Middle East, Egypt’s Amr Khaled, has said there were positive sides to the uproar. The caricatures “were useful for Muslims and the Islamic world” because they prompted Muslims to stand up for the Prophet and for Islam, the television preacher told the German news agency dpa on Monday. The dispute “charged the batteries of Muslim youths, strengthened their faith and got them to stand up actively for their religion.”

Can a controversy that polarises people and leads to death and destruction be “useful” for a religion?
