[Pooya/Ali Commentary 37:4] The unity of Allah is the most important message of the Quran. Man has to know that he has not been created by a mere accident or as sport by any vain creative power or by any contending forces or by any purposeless mechanical process. Man must know who is his creator and master and what are His qualities and powers and His rights over His creation. The belief in the unity of Allah is so important and so essential for man that its significance has been frequently mentioned in the Quran. In this connection refer particularly to the introduction of al Fatihah, commentary of Fatihah: 1 to 4 and Baqarah: 255.
