There is a Muslim passenger in a taxi .
He asks the taxi-driver to turn off the radio.
He explains that he must not hear music as decreed by his religion, for in the time of the prophet, there was no music ... no radio.
So the driver turns off the radio, stops the car, leans over and opens the back door.
The Arab asks him: "What are you doing?"
The driver replied: "In the time of the prophet there were no taxis, so get your ass out of my car and wait for a camel.”
