THIS work does not profess to be a life of Muhammad. It is a history of
   the development of the Qur'an, showing how its gradual formation was
   determined by the events of the Prophet's life. Treated in this way, the
   Qur'an reveals his change of position towards the various classes of persons
   with whom he was brought into contact, and by the aptness of its injunctions,
   its apologies, its denunciations, we are enabled to see how admirably this
   piecemeal ' revelation was fitted to meet the requirements of Islam as they
   arose.
   For the dates and the order of the Suras, or chapters of the Qur'an, I
   have followed Nöldeke's Geschichte des Qorans, which seems to me to be
   the best and most authoritative book on the subject. The following table
   shows the order in which Nöldeke arranges the Suras. He divides the Meccan
   ones into three groups, the earlier, middle, and later periods, and places
   all the Medina Suras in a fourth group.
   
   MECCAN SURAS First Period.From the first to the fifth year of the
   Prophet's Mission. A.D. 612-17.
