PS I want to thank Badr Al-Hajj in London for rushing me a copy of the book. I don't normally thank people for gifts they give me. But Badr, also obtained for me a very rare Arabic book from the 19th century that I have been desperately looking for (Diwan Mutanabbi edited by Nasir Yaziji). That gift meant the world to me. And other books he has sent me.
PSS I will revisit this book for a longer review.
