Surah 27. An-Naml, Ayah 60

The order, beauty, and grandeur of the Universe are appealed to. They show unity of design and purpose. How can unjust, ignorant, foolish, heedless, false men think of a multiplicity of gods, or of any god, besides the One True God?

To make a single seed germinate and grow into a tree is beyond man's power. When it comes to a great well-laid-out garden of beauty and delight, no one would think it grew up of itself without a Gardener's consummate art. And the orchard is more than the trees in it: there is design and beauty in their arrangement: proper spaces have to be left between them for the growth of their roots, for the aeration of the soil beneath them, and for the penetration of air and sunlight between their branches. How can any one then think of the wonderful Universe as a whole, without thinking of the far higher Unity of Design, the evidence of the One True Allah?
