Two Christians were lost in the Sahara desert . One is called George one is called Micheal . They were dying of hunger and thirst when they suddenly came upon an oasis , with what looked like an emirat of a mosque in the middle . Micheal said to George : "Look let's pretend we are muslim, otherwise these Arabs are going to kill us . I am going to call my self Mohammed." George refused to change his name , he said :" My name is george , and I will not pretend to be other than but what I am . ...George ." The Immam of the mosque received both well and asked about their names . Micheal said : "My name is Mohammed ." George said : My name is George. " The Immam turned to the helpers of the mosque and said : " Please bring some food and water for George only ." Then he turned to the other and said : " Well Mohammed I hope you are aware that we are still in the holy month of Rhamadan ."
