One was called David, the other Michael.

They were dying of hunger and thirst, when they suddenly and unexpectedly came upon an oasis, with what looked like an emirate with a mosque in the middle.

David said to Michael, "look, lets pretend we're Muslims, otherwise we won't get any food or drink. I'm going to call myself Mohammed."

Michael refused to change his name, he said: "My name is Michael and i won't pretend to be someone else."

The Imam of the mosque received both well and asked them their names. David said "My name is Mohammed" and Michael replied, "My name is Michael".

The Imam turned to the helpers of the mosque and said "Please bring some food and water for Michael Only." and then he turned to David, continuing "Salaam brother, Ramadan Mubarak..."
