Here's a great book, and this for two main reasons: - Because it is translated from the English and not Arabic. The books translated from Arabic are generally carnage while the Arabic originals are jewelry. - Because work e Martin Lings (on this subject because I do not agree with him on a multitude of other subjects) is remarkable. It includes the serious researcher and rigor of the Muslim traditionalist. The result is sublime. And for such a book, the price is justified. We are not disappointed. It is a book that we keep.
