And We send down the Book -the Quran- to you O Muhammad only to serve Allah's purpose and be of service in effecting Allah's object of illucidating to the various sects and to the people at large the strained points upon which the whole unreasoning turns and the points in the heat of dispute. 1t is the spirit of truth that guides into all truth as well as a mercy to those whose hearts are imprinted with the image of religious and spiritual virtues.
