[Lukongsimi]

A Chinese man searching for the mosque stops to ask a Moslem man for directions.  
C: "Excuse me, where is the mosque?"  

The moslem man looks at him suspiciously
M: "First, prove to me that you are a Muslim."  

The Chinese man, feeling hesitant and uncertain, suddenly responds,  
C: "go bite your father's p_nis!"  

A smile spreads across the Muslim man's face.  
M: "You truly are a follower of the Prophet!"

How to say in Malay?
