God maintains the temperature of the Earth in equilibrium and ensures the continuity of that equilibrium. If the temperature were to rise a little the ice caps would melt and the equilibrium on Earth be destroyed. But no such thing happens. This equilibrium ordained on Earth and in the entire universe is constantly maintained. If the heat of the Sun were to rise a little the whole of our galaxy would be affected. But the order determined by God is perfectly stable, and God ensures that it is constantly and uninterruptedly maintained. A similar picture was produced in the world-famous film The Day After Tomorrow, in which a storm suddenly arose and the air began to freeze, so quickly that a helicopter suddenly freezes and the people inside it freeze to death in a matter of seconds.
The fact that the Earth constantly follows a safe and regular course in this giant universe is a sign of faith that people must reflect deeply on. God shows us His infinite might. Anyone with an open mind will realise his own helplessness in the face of the might of God by way of these signs leading to faith, and will see that he has no power to do anything unless God so wishes. In one verse of the Holy Qur’an God says:
We made the sky a preserved and protected roof yet still they turn away from Our Signs. It is He who created night and day and the sun and moon, each one swimming in a sphere. (Sura al-Anbiya’, 32-33)
