Here Allah glorifies Himself and praises the beauty He created in the heavens of Al-Buruj, the giant stars, according to the view of Mujahid, Sa`id bin Jubayr, Abu Salih, Al-Hasan and Qatadah. This is like the Ayah,
Glorious is the One who made stellar formations in the sky and placed therein a lamp (sun) and a bright moon. [ 61] And He is the One who made the day and the night following each other, for the one who wishes to be mindful or wishes to show gratitude. [ 62] - 25:61-62.
In these two verses it is explained that Allah Ta’ ala has created the sun, the moon and stars which bring about the day and night (on earth) alternately, so that those who give thought to things around them should see manifestation of His omnipotence and proof His Oneness; and the thanks-givers should have occasion for thanks-giving. Therefore, whosoever does not pay heed to manifestation of His creation and does not offer Him his gratitude lives a useless life, and he has lost his capital as well (اللَّھُمّ اجعلنا من الذاکرین الشاکرین).
Among the numerous phenomena of our solar system is the constant revolution of the earth around the sun. Its revolution has a fixed orbit and is completed in one year. Due to the elliptical shape of its orbit and the sun not being at its exact centre, the different seasons occur. Besides its revolution, the earth rotates on its axis and this is completed in twenty-four hours. This rotation is the cause of day and night. In the vastness of space, the revolution and rotation of the earth with extreme precision and their being greatly subservient to human beings’ interests, are the most wonderful of happenings. One who ponders over these blessings will be overwhelmed with feelings of gratitude to God.
