       And we tried - and from God to pay - that the subjects of this book be separate and not confined to a specific science or a special chapter, so that every reader takes what is appropriate for them.
       We ask the Almighty Haqq to make the words of this book valid to bear on it the benefits it overflows with for His servants, since there is no benefit except from Him, glory be to Him, it is the source of the benefits and the principle of returns.
