﴿ قُلْ مَن رَّبُّ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ قُلِ ٱللَّهُ ۚ قُلْ أَفَٱتَّخَذْتُم مِّن دُونِهِۦٓ أَوْلِيَآءَ لَا يَمْلِكُونَ لِأَنفُسِهِمْ نَفْعًۭا وَلَا ضَرًّۭا ۚ قُلْ هَلْ يَسْتَوِى ٱلْأَعْمَىٰ وَٱلْبَصِيرُ أَمْ هَلْ تَسْتَوِى ٱلظُّلُمَٰتُ وَٱلنُّورُ ۗ أَمْ جَعَلُوا۟ لِلَّهِ شُرَكَآءَ خَلَقُوا۟ كَخَلْقِهِۦ فَتَشَٰبَهَ ٱلْخَلْقُ عَلَيْهِمْ ۚ قُلِ ٱللَّهُ خَٰلِقُ كُلِّ شَىْءٍۢ وَهُوَ ٱلْوَٰحِدُ ٱلْقَهَّٰرُ ﴾

“Say: "Who is the Sustainer of the heavens and the earth?" Say: "[It is] God." Say: "[Why,] then, do you take for your protectors, instead of Him, such as have it not within their power to bring benefit to, or avert harm from, themselves?" Say: "Can the blind and the seeing be deemed equal? -or can the depths of darkness and the light be deemed equal?" Or do they [really] believe that there are, side by side with God, other divine powers that have created the like of what He creates, so that this act of creation appears to them to be similar [to His]? Say: "God is the Creator of all things; and He is the One who holds absolute sway over all that exists."”

God expects man to bow down before Him. This ‘bowing down’, is the religion of the whole universe. Everything in this world is totally subject to God’s command. A physical sign of this subjection is the casting of shadows towards the west in the morning and towards the east in the evening. This daily happening is the material symbolising of that self-prostration which man is expected consciously to perform. A study of the universe in all its vastness reveals that all of it is bound by one universal law. This proves the fact that its Creator and Lord is one and only one. Rational and intellectual studies do not in any way prove that more than one power is active in this universe. In view of this, the notion of an additional god other than the one and only God is an absolutely baseless presumption. Observation with the help of the ‘eye’ indicates the existence of one and only one God. So, those who believe in the existence of more than one God, only prove their ‘blindness’, that they have assumed the existence of many gods due to their blindness and not on the basis of knowledge and observation in the real sense.
