Do you believe that quran is protected ?
If so why didn't Allah protect the book of the Jews and Christians and why didn't Allah just create a tablet that couldn't be corrupted by any man ?
I mean,he created the whole freaking universe and he can't even protect his little book from being corrupted by puny humans ?
Why does Allah blame and punish humankind,when he is the author and engineer of everything ever created ? Is he mental ?
