God has placed man in a world in which every thing and indeed the entire atmosphere bear testimony to the unity of God. But man does not avail of the light of guidance from it. He goes so far astray that he builds the system of his life on the basis of polytheism instead of the unity of God. If a servant of God takes up the task of proclaiming the unity of God, he meets with dire opposition. However, the preacher of Truth is not allowed to go to the extent of indulging in violence. He has to pursue his mission keeping himself within the sphere of advice and admonition or persuasion. If his call is not being effective, it is not his duty to add violence to his preaching. The only additions he can make consist of praying to God, ending all material or worldly quarrels unilaterally and influencing people’s hearts by selflessness and good behaviour.
