4:40 Actually, I have heard the version the Sultan who didn't kill St. Francis thought he was mad, and their religion orders them to protect madmen.

Think of this if you ever hear anyone saying I am mad, he may have got that from Muslims.

And if you hear it from a priest, think of the one who was going to pray at the Mosque!
