An  Muslim enters a taxi cab in. Once he is seated he asks the cab driver to “turn off the radio because he must not hear music as decreed by his religion and in the time of the prophet, there was no music, especially Western music, which is music of the infidel's and certainly no radio.” So the cab driver politely switches off the radio, pulls over to the side, stops the cab and opens the back door. The Musliim asks him: “What are you doing, man?” The driver answers: “In the time of the prophet there were no taxis.  So get out, stand on the curb and wait for a camel.”
