سَنُرِيهِمْ آيَاتِنَا فِي الْآفَاقِ وَفِي أَنْفُسِهِمْ حَتَّى يَتَبَيَّنَ لَهُمْ أَنَّهُ الْحَقُّ أَوَلَمْ يَكْفِ بِرَبِّكَ أَنَّهُ عَلَى كُلِّ شَيْءٍ شَهِيدٌ
“Soon We shall show them Our signs in the horizons and in their own souls until it becomes clear to them that He is the Real. Is it not sufficient that your Lord is wit- ness to all things?” (41:53) This blessed verse solely treats of Divine Unity and the manifestation of the signs of Truth in horizons and souls. Signs of the horizon include creation of the sun, the moon, and the stars with the order governing them, creation of all kinds of animals, plants, mountains, and seas with their innumerable wonders and mysterious creatures whose novel mysteries are unraveled in time and each of which demonstrates the Truth of His Pure Essence.
Signs of the soul include creation of different systems of human body, the order governing the wondrous mechanisms of brain and the systematic movements of heart, blood vessels, textures, and bones, and coagulation of semen and growth of embryo in the womb, and above all, the mysteries and wonders of human soul each aspect of which reveals the Omni- science of Allah Almighty, the Creator of the world.
All books on natural sciences and anthropology in all their dimensions serve as expositions of Divine Unity and knowing God, since they generally unravel wondrous mysteries which demonstrate the Omniscience and Omnipotence of the Creator of this world. At times, a scientist devotes all his life to one of these sciences, or one branch from amongst tens of branches of one of these sciences, but at the end of his life, he regrets that he knows nothing about that branch and his limited knowledge has made him perceive the depth of his ignorance.
This blessed verse is complemented with a beauteous and meaningful sentence, “Is it not sufficient that your Lord is witness to all things?”
What signs are more evident than the Manifestation of His Omnipotence through Creation of all creatures, leaves of trees, petals of flowers, mysterious layers of brain, delicate multilayer membranes of eyes, the face of the sky, the heart of the earth, and in short, all creatures demonstrate the signs of Divine Unity and bear witness to Divine Creation of the world. He is the Self-Sufficient Creator of the world, everything relies on Him and He bestows existence on all other beings
