2 christians were stranded in a desert.

The first was called John and the second was called Jack. They were extremely hungry and thirsty.

In the distance, they saw a mosque gleaming in the middle of no where.

John suggested to go and pay the mosque's Imam a visit and ask for some food and water. Jack agreed but suggested to change their names to islamic ones so that the Imam would agree to feed them.

John: That is pointless and deceiving. We should introduce ourselves with our real names.

Jack: No, or else they won't feed us. From now on call me Mohammed.

They made their way to the mosque and met the Imam and told him about their despair.

The Imam told John: We have a room filled with food and water. As for you Mohammed, have a blessed Ramadan.
