﴿ ٱلَّذِينَ يَذْكُرُونَ ٱللَّهَ قِيَٰمًۭا وَقُعُودًۭا وَعَلَىٰ جُنُوبِهِمْ وَيَتَفَكَّرُونَ فِى خَلْقِ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ رَبَّنَا مَا خَلَقْتَ هَٰذَا بَٰطِلًۭا سُبْحَٰنَكَ فَقِنَا عَذَابَ ٱلنَّارِ ﴾

“[and] who remember God when they stand, and when they sit, and when they lie down to sleep, and [thus] reflect on the creation of the heavens and the earth: "O our Sustainer! Thou hast not created [aught of] this without meaning and purpose. Limitless art Thou in Thy glory! Keep us safe, then, from suffering through fire!”

The universe with its whole existence is a silent declaration of God’s presence. When man removes the man-made veils from his eyes and unstops his ears, he starts seeing and hearing this silent announcement all around him. It then appears improbable to him that, in a universe where the stars and the planets have continued to exist for millions of years, man may cease to exist within fifty or a hundred years, taking with him to his grave all his desires and aspirations. In a world which abounds in the beauties of nature, with the fragrance of flowers, where countless meaningful blessings, like air, water and the sun have been provided, should man’s end be nothing but only sorrow and suffering? Then he also finds it unthinkable that, in a world of limitless possibilities where, just by sowing seeds in the ground, a whole forest of trees comes into existence, one should fail to receive the fruits of virtuous actions; that in a world where the sun shines daily after the dark night, centuries go by without being illuminated by the lustre of fairness and justice; that in a world where earthquakes and tempests lie dormant, man should continue to perpetrate tyranny and oppression without ever being checked.
