If there had been in them (the heavens and earth) any gods except Allah, they would both have certainly been in a state of disorder (Q. 21:22). The Qurʾān calls us to reflect, if there were multiple gods in the heavens in the earth, it would have been chaos and disarray. The order of the heavens and the earth is a sign of God’s Oneness. Likewise the heart, if it has in it any object of worship other than God it will be corrupted to an extent which can only be rectified by removing that object of worship from it and God alone must be its God and its object of worship which the person loves, longs for, and fears, puts his trust in, and turns to.
