1. Intellectual Proof for the Existence of Allah
This universe runs in perfect order which cannot be interrupted. Its parts do not clash or collide into one another. "It is not for the sun to overtake the moon, nor does the night outstrip the day. They all float, each in an orbit." [Soorah Ya-Sin (36): 40]
Is it logical that this enormous universe with its perfect order could be the creator of itself?
No, it is not. This universe cannot be the creator of itself because this would mean that nothingness brought the creation into existence whereas nothingness cannot originate. So, it is impossible that this universe could be the creator of itself.
It is also not possible that this great universe could be a result of coincidence because it is running in a steady and marvelous order. Whenever there is a coincidence, it is more likely that it will not cause order. It is not possible that there occurs a coincidence except that it brings interruption.
Abu Hanifa (rahimahullah) was known for his intelligence and so there came to him a group of atheists asking him to prove the Existence of Allah.
Imam Abu Hanifa said, "Let me think," then he remarked, "I am thinking about a loaded ship that was tied to a port. The cargo unloaded itself without
porters and the ship sailed away without a captain.”
(Upon hearing this,) the atheists declared, "How can you say something like this! This is impossible. We cannot believe in it.”
Imam Abu Hanifa (rahimahullah) replied, "If you do not believe in this then how do you believe in the sun, the moon, the stars, the sky and the earth – how can you believe that all these came into existence without an Originator?"
Allah points out this intellectual proof in His Saying, "Were they created by nothing or were they themselves the creators?" [Soorah at-Tur (52): 35]
A Bedouin was asked, "How do you know your Lord?"
The Bedouin could only reply with (the example of) that which was before him, so he said, "Droppings tell of a camel. Foot-prints tell of a traveler. The sky, the earth with mountain passes, seas with waves -do they not tell of the All-Hearer, the All-Seer?"
-Yes (they do), without doubt.
Shaikh Saleh ibn Fawzan al-Fawzan writes in Aqeedah at-Tawheed,
It is instinctively known even to a young child that if he is hit then there surely exists someone (or something) which caused it. So although he may have not seen the doer, he will ask, 'Who hit me?'
If he is told, 'Nobody hit you,' – it will not be acceptable to his mind that the hitting occurred without a doer...
This is why Allah says, 'Were they created by nothing, or were they themselves the creators?' [Soorah Toor (52): 35]
This verse mentions limited possibilities. Moreover, Allah mentions them in a negative form in order to assert that (the answer to) this is known by necessity and cannot be denied. He says, "Were they created by nothing?" meaning without a Creator? or did they create themselves? Verily, both these matters are false.
It is thus established that there exists a Creator Who Created them and He is Allah -there is no creator other than Him. Allah says, "This is the creation of Allah. So, show Me that which those (whom you worship) besides Him have created." [Soorah Luqman (31): 11] "Verily! Those whom you call upon besides Allah, cannot create (even) a fly, even if they combine together for the purpose." [Soorah al-Hajj (22): 73]
Although this challenge has been repeatedly brought up, no one has ever claimed to create anything. So, it is established that Allah is the Sole Creator, Who has no partners.”
