Does Allah exist? And if He exists, show me His form!

In the Name of Allah, the All-beneficent, the All-merciful
Peace be upon you, and the mercy of Allah and His blessings
Half of the question indicates reason, and the other half indicates ignorance or insincere disputation..

As for the question whether Allah really exists or not: the answer is that He exists, and the proofs of His existence are many.
All human minds have agreed that there is no made thing without a maker; so there is no created thing without a creator. We observe abundant creation, and this indicates that it has a Creator who brought it into being..
Perhaps some err in expression: one does not know whether he wants an answer to the question, Does Allah exist? or the question, Is Allah one? or some other question..
Each question has its precise answer, which requires reflection from us despite its simplicity..
For the truth is simple, and since Allah wanted all human beings to believe in Him, He made it simple and easy, for He created all human beings upon the innate nature (fiṭra) that can lead one to guidance..
The first question was about the existence of Allah, that is, about the very existence of a God and Creator of this universe. Its proof is the proof of reason and of the innate nature, about which no two people disagree: since creation exists by sense-perception, by direct observation and by agreement among all people, then the Creator of this existence exists before it, and He is the One who created it..

Another question may come: Where is the One who created this? And what is our duty toward that God? These are other questions..
Their answer, in all brevity, is that the Creator is Allah, the One, the Unique, and He is so for several proofs, among them the proof that there is none but Allah who has claimed the creation of the universe and of creation, and He sent prophets who made Him known to people, and they had the signs and proofs..
And no one has claimed that..
Also, it is the proof of reason that gives us knowledge that Allah is One, without partner, because of the harmony we have seen in the universe and in its precise motion.. This is proof that the Creator is one.. And the prophets, too, informed of that and emphasized it..

Here is a question that everyone who does not believe in the existence of Allah and the existence of the Creator must ask—he must ask himself frankly and clearly—namely: (If there is no Creator of the universe, then who brought into existence this precise creation, with all wisdom??
He must answer this question precisely and convincingly to himself..
And he must answer the question: If Allah the Exalted is not the Creator, then who created this universe? Has anyone claimed that? And what is his proof?

Unfortunately, some raise objections and make themselves doubt by them, in order to flee from the truths. But seriousness means finding answers, either for the reason for one's rejection or for the alternative.. The more a person thinks with this seriousness, the more he is guided to the truths, because he will be concerned with obtaining answers..

As for the second question, or the second part of the question, about (If He exists, show me His form).. it is a fundamentally mistaken question..
The reason for that is that when we search for the truth, we do not ask that the truth be tailored to our demands or our measurements; rather, we must search for the questions in order to obtain the answers that correspond to the truth..
The phrase “show me His form” means that he does not believe in things except those he sees. If he searched seriously and stood with himself frankly, he would find that he believes in many things that he has not seen.. such as laws, such as electricity, and so on.. Indeed, we now find that astronomers believe in much information that keeps emerging for them, which they have not seen except through calculations ...
If we asked him whether he could distinguish between a wire through which electric power passes and a wire in which there is no such power, he would not be able to, except through the effects and indications..
Likewise faith in Allah the Exalted: we cannot believe in Him except through His indications that point to His existence..

These subjects undoubtedly require attention from the person if he is serious.. and they require study; and, if Allah wills, he will reach the truth, for every human being is capable of that, except the obstinate..

This is in brief, and I ask Allah that there be some benefit in it..
My greetings and my prayers
