In the previous verse, the word ended in the oneness and unity of God. Here it begins a reasoning and mention of the unity of purpose and design throughout the nature which may lead to the knowledge of HIS existence and manifestation of HIS attributes, through their effects.

      Let us notify first that, always and everywhere, an arrangement, and a good order, is the evidence of knowledge and wisdom, and everywhere and all the time co-operation, and collective action, is a proof of unity of purpose and oneness of design and designer.

      Through the verse under discussion, in the following six parts, effects of the good order and unity of purpose and design that dominates over the universe, are put to light:

      1- It begins with the glory of the heavens and earth and the wonderful extensive space around us saying :``In the creation of the heavens and the earth there are signs for people who use their wisdom.''

      scientists have revealed that millions of galaxies like this milky way of ours, are seen overhead in the spacious space with aided or unaided eyes, so much so that our own solar system among them seems to be like a droplet in an ocean! Only in our milky way there moves on their own orbit hundreds of millions of suns and bright stars!

According to recent theories and views of scientific researchers many thousands of these planets, like our own globe are inhabited and occupied by living creatures in the widest diversity of nature! Lo! What a grandeur and greatness, and what a power and ability of creator and creation!

      2- The verse then points at the most striking everyday phenomenon, that results from interrelations of heaven and the earth; such as the alternation of day and night, changing regularly in duration and bringing forth various seasons and the warm and cold latitudes of our globe - the night for rest and the day for work. In this relation the verse implies: ``And in the alternation of night and day, there are signs for those people who use their wisdom.''

      3- And the stately and huge ships that sail across the oceans for merchandise and other benefits of man. Thus the sea serves us no less than the land, hence the verse: ``And the ship that sails across the sea for what profits people.''

      4- God's Grace and Favour to man and all the living creatures on the earth are further exempilfied by the rain which leads to the fertility of land, and by the verse, Allah calls to our mind the winter's death of nature, as well as the revivification of the spring, which is a sample and sign of nature's resurrection and raise of the dead bodies. In this case the HOLY BOOK says: ``And (THINK OF)the water that Allah sent down from the sky therewith reviving the earth after its death.''

      5- The verse also makes a mention of the wonderful winds; driving the clouds in the skies. It also drives the ships across the seas. The wind also impregnates and fertilizes the trees, to make them fruitful by scattering the seeds here and there and this way and that. The wind also serves to move the polluted air which is rendered unclean, replacing it with pure air for breathing, which is vital for the life.

      6- Once again the clouds are called to mind, that are made as subservient as slaves, between the sky amd the earth. At mid-day they temper the glare of the sun, and all the time they affect and control the dangerous radiations, such as that of the ultraviolate an infrared rays. Surely in all these signs that were mentioned here, the greatness and infinite knowledge and extensive mercy of God can be seen.
