﴿ يُولِجُ ٱلَّيْلَ فِى ٱلنَّهَارِ وَيُولِجُ ٱلنَّهَارَ فِى ٱلَّيْلِ وَسَخَّرَ ٱلشَّمْسَ وَٱلْقَمَرَ كُلٌّۭ يَجْرِى لِأَجَلٍۢ مُّسَمًّۭى ۚ ذَٰلِكُمُ ٱللَّهُ رَبُّكُمْ لَهُ ٱلْمُلْكُ ۚ وَٱلَّذِينَ تَدْعُونَ مِن دُونِهِۦ مَا يَمْلِكُونَ مِن قِطْمِيرٍ ﴾

“He makes the night grow longer by shortening the day, and He makes the day grow longer by shortening the night; and He has made the sun and the moon subservient [to His laws], each running its course for a term set [by Him]. Thus is God, your Sustainer: unto Him belongs all dominion - whereas those whom you invoke instead of Him do not own so much as the husk of a date-stone!”

There is a large store of water on the earth—salt water in the oceans and seas, and fresh water in rivers, lakes and springs. This water is the source of innumerable advantages for man. It is used for drinking and irrigation. The creatures which live in water provide valuable food for man. The oceans and seas, spread over three-fourths of the Earth enable transportation and form a vast storehouse of valuable objects like pearls, mineral ores, etc. God causes the earth to revolve around the sun and rotate on its axis in a regulated manner, thereby causing the seasons, and the alternation of day and night. There are similar innumerable arrangements which have been brought into being by the all-powerful God. As such, who else is there other than God who deserves man’s utmost gratitude? It is God with His unfathomable powers who can fulfill the needs of man, and not those imaginary gods who possess absolutely no powers.
