This Muslim dies and goes to heaven.
When he gets there St. Peter meets him at the gate and says, "Welcome to heaven my son, please enter."
The Muslim says "oh no no, I can not enter without seeing Allah."
St. Peter says "oh...Allah, he is upstairs."
Muslim: "of course, Allah is upstairs."
He climbs upstairs and meets Jesus Jesus says "welcome to heaven my child, please enter."
The Muslim says "Oh no no, I can not enter without seeing Allah."
Jesus says "but of course...Allah is upstairs, top floor."
The Muslim smiles and thinks to himself "of course, Allah is on the top of heaven."
At the final gate he meets the all mighty Lord himself who says "welcome to heaven my child, please enter."
Of course the Muslim says he can not enter without meeting Allah, to which the Lord replies.
"But of course...Allah is here. But he is busy right now, why don't you have a seat and wait for him."
The Muslim is so excited that his Allah is so important, after all he thought is was so.
The Lord says to the Muslim "why you must be parched, would you like a drink?"
Muslim "yes I would like a drink."
Lord "would you like a coke?"
Muslim "yes it sounds good."
Lord "fine, I think I'll join you" with that the Lord snaps his fingers and says
"Allah, bring two cokes."
