"If you turn your backs, I have transmitted to you what I was sent to you with; my Lord will replace you with another people, and you will not harm Him at all. My Lord is the Preserver of everything." (Surah Hud, 11:57)
Today, all of our scientific data indicates that the universe was brought into existence from nonexistence. Those atoms that existed when the universe first came into existence, and those that make up every living and non-living being today, are the very same atoms. Science further verifies that the number of atoms in existence has never changed. Those atoms, which spread at a tremendous speed throughout the universe after it came into existence, today make up stars, Earth, the air, water on Earth's surface and even in your body. The fact that they accomplish this with such a superior order reveals the existence of the Power that controls each atom, for the existence of this order necessitates the existence of the Power that establishes it.
At this point, we come across one fact: Allah, Who created matter from non-existence and established a flawless order, surely knows about each stage of this process, for even a single second of such an intricate and complex system could not have formed randomly. This fact reveals His infinite power. Moreover, He continues to observe and protect this order. The verse, “Your Lord is always watching” (Surah al-Fajr, 89:14) reveals Allah's everlasting protection of the universe:
We know exactly how the earth eats them away. We possess an all-preserving Book. (Surat al-Qaf, 50:4)
He had no authority over them, except to enable Us to know those who believe in the Hereafter from those who are in doubt about it. Your Lord is the Preserver of all things. (Surah Saba, 34:21)
As for those who take others besides Him as protectors, Allah takes care of them. You are not set over them as a guardian. (Surat ash-Shura, 42:6)
The Prophet (saas) said:
“Be mindful of Allah and He will protect you. Be mindful of Allah, and you will find Him in front of you.” (Hadith at-Tirmidhi)
