Have you read Road to Makkah by Muhammad Asad? It reads similar to your writing and I greatly enjoyed it. After reading your article, I think that book merits a reread for me.
I haven't read it but I've heard great things about it. I've read his translation of the Quran though...he was a gifted writer and scholar. What a luminary! http://en.wikipedia.org/wiki/Muhammad_Asad
