Wa aleikum as-salam wa rahmatullahi wa baraketuh,
Thanks brother Abdullah Almadi, I have read this article before, but frankly for me those various quotation are merely agreements of contemporary scholars and that's all. The real, historical proof is that one I've discussed above. Of course the documents from Ptolemy, Diodorus and other ancient geographers are also a historical evidence, but are not so clearly expressed about Mecca, in contrary to the two sources which I've presented in this post.
By the way, brother Osama, the title of this thread should be changed to "Historical proof of Mecca existence B.C." and insha'Allah perhaps will be a new findings.
