Correspondents visited mosques from Nigeria to Indonesia this month to listen to the sermons of the imams. Have the mosques been transformed from a place of prayer into a hotbed of extremism and center of Islamist indoctrination? Radical preachers have actively contributed to this impression. In a Berlin mosque, a television crew secretly recorded the sermon of a Turkish imam who described the Germans as godless and railed against their alleged stench. In London, hate preacher Abu Hamza al-Masri called upon the faithful to murder improperly clad female tourists in his native Egypt. Other agents of the Koran speak moderately when addressing Western audiences, but their words turn decidedly more radical when directed towards Muslims.
