17 CD SET, The suffering of the world is spoken of in term of wars, starvation, hatred, competition, and the struggle of the survival of the fittest. Yet all the suffering of the world originates in the human heart. Every crime committed, every act of oppression, every callous cruelty, and every injustice to the self or others emanates from the hearts of men. The soundest of hearts was the heart of the Messenger of Allah (peace be upon him) who, through his purity and singularity of intention, transformed the world. His teaching remains and the challenge is for each of us to take it and to transform our hearts with it, thereby, transforming the very world in which we live.
