God has to always exist.  Jesus (’alaihiss’salâm)  was a child; then he grew up. He ate and drank. He slept, woke up and walked. He needed many things in order to stay alive, as any man would. Can a needy person ever be free from want? Can something which has come into being after having been nonexistent exist eternally? Can a changing object exist eternally?
Imâm-ı Fahreddin Râzî (rahmatullahi ’alaih), the great Islâmic savant, the author of Tafsîr-i kabîr and also of various other valuable books, wrote while interpreting the sixty-first âyat of Sûrat-u Âl-i ’Imrân:
When I was in Khâwarezm, I heard that a priest came to the city and that he was striving to spread Christianity. I called on him. We began to talk. He asked what was the evidence to demonstrate the fact that Muhammad (alayhissalâm) was the Prophet. I answered him:
Fahredin Râzî – As it is communicated that Mûsâ, Îsâ and other prophets (’alaihimussalâm) demonstrated wonders and miracles, so we read and hear about the miracles of Hadrat Muhammad (alahissalâm). This news is unanimous. You are free to accept or refuse these unanimous reports. If you refuse and say that manifesting miracles does not signify prophethood, you will have to disbelieve the other prophets, too. If you admit that the reports transmitted in a common way are correct, and that the person who performs miracles is a prophet, you will have to admit that Muhammad (’alaihi’s-salâm) was a prophet, too. For, Muhammad (’alaihi’s-salâm) performed miracles and those miracles were communicated to us commonly and unanimously so they must be dependable. Since you believe the other prophets because of the fact that they performed miracles, which also were communicated commonly and unanimously, you have to believe that Muhammad (’alaihi’s-salâm) was a prophet, also.
Priest – I believe that Îsâ (’alaihi’s-salâm) was a god, not a prophet.
[God means idol. All the things that are worshipped are called ‘god.’ The name of Allâhu ta’âlâ is ‘Allah,’ not ‘god.’ There is no ‘god’ except Allâhu ta’âlâ. It is wrong to use the word god instead of Allah.].
Fahreddin Râzî – Now we are talking about ‘Prophethood.’ We should understand first ‘what prophethood is’ before talking about ‘Divinity.’ Moreover, your claiming that Jesus (’alaihiss’salâm) was God is completely false. God has to always exist. Then, substances, objects, things that occupy a place cannot be gods. Îsâ ‘alaihis-salâm’ was a substance. He came into being after he had been nonexistent and, according to you, he was killed. Formerly, he was a child; then he grew up. He ate and drank. He talked as we do now. He went to bed, slept, woke up and walked. He needed many things in order to stay alive, as any man would. Can a needy person ever be free from want? Can something which has come into being after having been nonexistent exist eternally? Can a changing object exist eternally?
You say that Jews caught and hanged Îsâ ‘alaihis-salâm’ though he ran away and hid himself. You say that Îsâ ‘alaihis-salâm’ was very sorrowful then. You say that he looked for ways to save himself from this plight. If he had been a god or a part of a god, wouldn’t he have protected himself against the Jews? Wouldn’t he have annihilated them? Why did he become sorrowful? Why did he look for a place to hide himself? By Allah! It amazes me to hear these words. How can these words be said and believed by a man who has a brain. Wisdom is a witness to prove that these words are false.
You say it in three different ways:
1- You claim that Jesus was a physical god who could be seen with the eyes. Saying that the God of creatures is Jesus (’alaihi’s-salâm), who was a human and a physical body, would mean that, when he was killed by the Jews, the God of creatures was killed. In this case, there would be no God for creatures in the end. Nonetheless, it is impossible for creatures not to have a God. Moreover, is it possible for someone to be unjustly caught and killed by the Jews and at the same time to be the God of creatures?
It has been commonly known that Jesus (’alaihi’s-salâm) used to worship Allâhu ta’âlâ profusely and was fond of ta’ât (obedience). If Jesus (’alaihi’s-salâm) had been God, he would not have worshipped, nor been fond of ta’ât. It is never possible for God to worship himself. [On the contrary, he is worshipped by others. So, it is understood that the words of the priest are nonsensical.]
2- You claim that God penetrated into him, and he is the son of God. This belief is wrong because God cannot be a substance or araz (attribute). It is impossible for God to penetrate into a substance. If God were a substance, He could penetrate another substance. If something penetrates into a substance it must be a substance, too, and after penetration, two substances will be mixed together. This requires God to be divided into pieces. If God were an araz (attribute), He would need a locality, a residence. And again, this would mean that God needed something else. Someone who needs something else cannot be God. [What was the reason for God penetrating into Jesus (’alaihi’s-salâm)? Penetration without a reason is ‘tarjîhun bilâ murajjeh.’ We have already proven that this is nonsense, and we have explained this fact in our book Could Not Answer, where we have also proven that Allâhu ta’âlâ is one.]
3- You say he is not God, but some part of God penetrated and settled into him. In this case, if the part that entered him is effective enough to make Him God, when the part left God, He would be incomplete in being God. If the part is not effective enough to become a God, this part cannot be deemed to be a part of God.
What is your proof to claim that Jesus (’alaihi’s-salâm) was God?
The priest – He is a god because he used to enliven the dead, cure the congenital blind, and heal the itchy white specks on the skin, which are called leprosy. These kinds of things can be done by God only.
Fahreddîn Râzî – If there is no proof, no sign to demonstrate the existence of something, can that thing be said to be non-existing? If you say that it can be said, and that it does not exist, you will have denied the existence of a Creator when you say that there was nothing eternally before. In this case your words will be nonsensical. It is because all creatures are proofs and signs which demonstrate the existence of Allâhu ta’âlâ.
If you say that the thing inferred through a proof may exist even if there is no proof, in this case, you will have accepted the existence of a Creator when there was nothing in the past eternity. If you say that when Jesus was nonexistent in the past eternity God penetrated into him, in this case, your claim will be something accepted without a proof. It is because Jesus was created later on. His existing in the past eternity means there is no proof. While you acccept, without proof, that God entered Jesus (’alaihi’s-salâm), how do you know that He has not entered me, you, animals or even plants and stones? Why do not you accept, without proof, that these also may be penetrated?
Priest – The reason why He entered Jesus (’alaihi’s-salâm), and did not enter you, me, or others, is clear. It is because he performed mu’jizas. No unusual things were performed by you, me, or others. Hence, it is understood that God penetrated into Jesus, but not any others.
Fahreddîn Râzî – You show his mu’jizas as a proof to claim that God entered him. How can you claim that unless we perform a mu’jiza God cannot enter? It is impossible for you to claim that God does not penetrate into you, me and others since we and they have not done unusual things. It is because we have already agreed with you that there is no need to prove the existence of the thing inferred. Hence, having been penetrated does not require one to perform mu’jizas, that is, unusual, extraordinary things. Then, you have to believe that God has entered me, you, the cat, the dog, and the rat. Then is it possible for a religion to be true that causes us to believe that God has entered these low creatures?
Making a snake from a stick must be more difficult than enlivening the dead, for the stick and the snake are not close to each other in any respect. While you do not call Hadrat Moses a god, or the son of God, though you believe that he made his rod turn into a snake, why do you call Hadrat Jesus God or such and such?
The priest, being unable to find an answer to these words of mine, had to stop talking.
[ Most of today’s Christians believe that the four Gospels authorized by the priestly Nicene Council are the true Injîl (Bible) that descended from heaven. Trinity, which is written in the Gospel of John, is the basis of their creed. “Îsâ (Jesus) is not a God. He is the Messenger of God. God, Who is One and eternal, loves him very much and makes and creates whatsoever he wants Him to. Therefore, from him do we ask for all our needs, and with this intention do we prostrate ourselves before him and before our idols, which are his representatives. ‘Father and Son’ means a person who is loved very much,” they say. “By ‘Son of God’ we mean that God loves him very much,” they say. Those who hold this belief are called the Ahl-i-kitâb (People of the Book). On the other hand, Christians who believe that Îsâ ‘’alaihi-s-salâm’ or any other creaturepossesses the attribute of Ulûhiyyat (deity) and who say, “He, too, is eternal, and he, too, creates everything,” become mushriks (polytheists). Since they deny (the prophethood of) Muhammad ‘’alaihis-salâm’, they all are non-Muslims and disbelievers.
Allâhu ta’âlâ creates good things with His Attribute ‘Rahmân’, and evils with His Attribute ‘Qahhâr’. In this world good and useful things are mixed with evils and harms. Allâhu ta’âlâ, being very merciful, created in man a special power to distinguish good deeds from evil ones. This power is termed ’aql (mind, wisdom, reason). And since the ’aql would be unable to do this job of discrimination in the full sense, Allâhu ta’âlâ Himself pitied His slaves and did this job of discrimination. Separating good and bad deeds from each other, He informed His slaves about them via His Prophets, commanding the good deeds and proscribing the evil ones. These commandments and interdictions of Allâhu ta’âlâ make up what has been called dîn (faith, religion).
The religion taught by Îsâ (Jesus) and that of Mûsâ (Moses) ‘’alaihimussalâm’ were interpolated by people with philosophical ideations written by Plato and the like. So those two religions lapsed into polytheistic cults, so that they no longer were heavenly religions. The dîn (religion taught by Muhammad ‘’alaihis-salâm’) is called Islam. A person who denies the fact that religions are revealed by Allâhu ta’âlâ, will become a kâfir (unbeliever, disbeliever).
A person who believes Muhammad ‘’alaihis-salâm’ and yet denies any other Prophet will have denied him, too. For, belief in Muhammad ‘’alaihis-salâm’ entails belief in all the other Prophets as well. Being a Muslim begets a civilization. And civilization, in its turn, does not mean to make jet planes and electronic devices; it means to use them not for perpetration of cruelty and oppression, but for serving mankind. Some European and American scientists are successful in their branches when they retreat from their religion. In contrast, some idiots with Muslim names experience failure when they get away from Islam. The reasons deserve an indepth analysis.]
