﴿ قَٰتِلُوا۟ ٱلَّذِينَ لَا يُؤْمِنُونَ بِٱللَّهِ وَلَا بِٱلْيَوْمِ ٱلْءَاخِرِ وَلَا يُحَرِّمُونَ مَا حَرَّمَ ٱللَّهُ وَرَسُولُهُۥ وَلَا يَدِينُونَ دِينَ ٱلْحَقِّ مِنَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ حَتَّىٰ يُعْطُوا۟ ٱلْجِزْيَةَ عَن يَدٍۢ وَهُمْ صَٰغِرُونَ ﴾

“[And] fight against those who - despite having been vouchsafed revelation [aforetime] -do not [truly] believe either in God or the Last Day, and do not consider forbidden that which God and His Apostle have forbidden, and do not follow the religion of truth [which God has enjoined upon them] till they [agree to] pay the exemption tax with a willing hand, after having been humbled [in war].”

If faith is active and alive, man attributes every event to God. He is able to understand a thing only when he forms an opinion about it with reference to God. He appreciates and understands the sweet smell of a flower when he finds the fragrance of God in it. He discovers the sum only when he comes to know of its donor. Every greatness seems to him the blessing of God. Every good reminds him of God’s Grace. Contrary to this, if man’s relation with God is reduced to the stage of a feeble belief, then God will become an unknown entity in the sphere of his active consciousness; he will start imagining God on the pattern of the visible things of the world. Those of feeble belief start seeing their Creator in the same way as they see the things of the world known to them. They bring the Creator down to the level of the created ones. This was the condition of the ancient Jews and the Christians during the period of their deviation from the true faith. At that time the concept of God they had was relegated to the position of a flimsy belief. Accordingly they started giving to their great ones and saints the status which they should have given to the All Knowing God, Who is Aware of the Unseen. They saw that the Greek and Roman nations had made the sun their god and had presumed the existence of a son of that god. So, they too felt that this was the highest ranking title for their great ones. They made their own interpretation of the words ab (father) and ibn (son) appearing in their Holy Books and started calling God ‘the father’ and each of their prophets His ‘son,’ though the fact is that God is One and only One; He is incomparable; He alone deserves to be accepted as the Greatest and most worthy of being worshipped.
