It has been stated in Answering Islam that "
Although, as we shall discover later, the presence of the number 19 in the Quran as presented by Dr. Khalifa, is impressive". Obviously the Answering Islam article had non-numerical objections to it, but nevertheless, they assert there is a vast presence of the number 19 in the Quran.
I think the only solution is for me (and you) to study this and see whether such a code exists in the Quran.
It just seems rather odd that an anti-Islamic site that is meant to refute Islam testified to the truth of the Code 19 in the Quran...there must be something serious to it and requires serious study.
