The author presents an analysis of the Koran that in an enlightened world would not be expected to excite controversy of any sort. The tone of the book is one of benevolent calm and carefully balanced reasoning that could hardly be expected to offend any person capable of sentient reflection. Most of the passages analyzed by the author would not seem to be on the verge of overturning Islam and the authority of the Koran. One passage of interest is the one in which Mary gives birth to Jesus. In this account there is an Arabic phrase indicating the existence of a streamlet from which Mary was able to drink while in labor. It is argued by the author, however, the original Aramaic version of this phrase states that the birth is legitimate (pp.141-142; Sura 19:24)) rather than that such a streamlit existed. Somewhat more controversial is the statement in the Koran that when rendered in Aramaic implies that its original language was indeed a foreign one and not Arabic (pp.123-124).
The topic that brought this book to the attention of the news media, that it is white raisins rather than willing virgins that the devout Muslim will encounter in Paradise, is given ample space. Indeed, pages 247-283 are devoted to this topic. The author regards his efforts as helping "the Koran to achieve its original inner coherence" (p.264) so that the notion of Paradise depicted by Ephraem the Syrian is restored to its proper place. The chapter "Virgins in Paradise" is followed by the chapter "The Boys of Paradise" (pp.284-291). Although the author does not suggest that any interpretation of the role of "boys" in such a place might be salacious, devout Muslims might take comfort in the author indicating that the Arabic word "walid" (i.e. boy or child), equivalent to the Aramaic word "yalda", is meant as a reference to "child of the vine"--that is, wine.
The reader of this book must have, at the very least, some knowledge of Arabic for this book to be at all comprehensible. Such knowledge of Arabic should be at an intermediate level, allowing the reader to parse verses of the Koran with the aid of a dictionary and an interlinear translation. The Aramaic phrases are written using the beautiful Estrangelo Syriac alphabet that can easily be found on the web, and which in some ways resembles the Hebrew alphabet.
As to the argument of the author that much of the Koran had originated from Aramaic texts, I must confess that I am not sufficiently expert in my knowledge of Arabic to make an independent assessment. As for my knowledge of Aramaic, it is quite rudimentary. Nevertheless, the book is sufficiently clearly argued for me to at least enjoy the discussion, and to imagine its import and relevance.
