Me: I bet you can read 3 books this summer. I’ll read 8 and who ever finishes their books by the end of the summer gets a prize
S went quiet for a while and thought about it
S: I know what my first book will be.
Me: really?
S: The Quran!
Me: That’s a really long book for you to read. It might take more than the summer.
S: You’re right… and it has a lot of difficult words as well.
Me: Yes, but you can read it slowly and take your time.
S: What would I get if I read it all?
Me: If you read all of the Quran? anything you like
S: UFFF! WALLAH? (Really?!)
Me: Yes.
Longer moment of silence passes
S: Mama… What’s the book God sent to Sayidina Moosa (Moses)? The Bible?
Me: No, the Torah.
S: Is it shorter than the Quran?

Gotta love the way kids think!
S is ever the bargainer. He tries to get what he wants in e easiest possible way ever.
HAHAHAHAHA… !!! Loved it!
LOL.
Then there is the Book given in 1974 and 1977 in Arès, France. I think it is even shorter, available in French, English and German, so far.
