According to the Muslim scripture, one of the unique names belong only to Allah is al-Haqq, i.e., the Truth:
Al-Haqq: The Truly Real
The Truth, the Real, the Really-existing, He whose existence and divinity are true, the One who creates according to the requirements of wisdom, justice, right, rightness, the Necessarily-existing by His own Essence, He whose existence is undeniable. Every reality exists from His essence and nothing has any intrinsic reality except Him.
Al-Haqq is one of the Ninety-Nine Names.
“That is because Allah – He is the Truth, and what you call upon besides Him is falsehood Allah is the All-High, the Most Great.” (31:29)
“On that Day Allah will pay them in full what is due to them, and they will know that Allah is the Clear Truth.” (24:25)
“That is because Allah is the Real and gives life to the dead and has power over all things and the Hour is coming without any doubt and Allah will raise up all those in the graves.” (22:6) (Aisha Bewley, The Divine Names; bold emphasis mine)
Islamic theology expressly teaches that such names and characteristics cannot be ascribed to a creature, nor can a mere created being attribute such qualities to his own person, since this would be an express claim to divinity. As such the individual would be committing shirk (“association”) by ascribing a partner with Allah in his exclusive divine attributes and titles. This is the one sin that Allah never forgives:
Who has made the earth a resting place for you, and the sky as a canopy, and sent down water (rain) from the sky and brought forth therewith fruits as a provision for you. Then do not set up rivals unto Allah (in worship) while you know (that He Alone has the right to be worshipped). S. 2:22 Hilali-Khan
Verily, Allah forgives not that partners should be set up with him in worship, but He forgives except that (anything else) to whom He pleases, and whoever sets up partners with Allah in worship, he has indeed invented a tremendous sin. S. 4:48 Hilali-Khan – Cf. 4:116
And indeed it has been revealed to you (O Muhammad), as it was to those (Allah’s Messengers) before you: “If you join others in worship with Allah, (then) surely (all) your deeds will be in vain, and you will certainly be among the losers.” S. 39:65 Hilali-Khan
In fact, the Islamic sources attest that two Muslims were brutally killed for ascribing certain qualities of Allah to themselves. One of them was put death for claiming to be the truth!
In the days of the ‘Abbasid caliph, al-Muqtadir, the fuqaha’ of Baghdad among the Malikis and the Qadi of the Qadis, Abu ‘Umar al-Maliki, agreed to kill al-Hallaj and crucify him for his laying claim to divinity and incarnation and his words, “I am the Truth,” even though he outwardly kept to the Shari‘a. They did not accept his repentance.
That is also how they judged Ibn Abi’l-Faraqid1 who made a similar claim to that of al-Hallaj later on in the time of the Caliph, ar-Radi billah. The Qadi of the Qadis of Baghdad at that time was Abu’l Husayn ibn Abi ‘Umar al-Maliki.
1. He was well-known in Baghdad. He claimed to be divine and said that he could bring the dead to life. The caliph ar-Radi billah ordered that he be arrested so he fled. After he was captured, he was judged to be an unbeliever and was executed in 322. (Qadi ‘Iyad Musa al-Yahsubi, Muhammad Messenger of Allah (Ash-Shifa of Qadi ‘Iyad), translated by Aisha Abdarrahman Bewley [Diwan Press Ltd., Revised edition 2011], Part Four. The judgements concerning those who think the Prophet imperfect or curse him, Chapter Three. Concerning the Judgement on Anyone Who Curses Allah, His Angels, His Prophets, His Books and the Family of the Prophet and His Companions, Section 6. The judgement on anyone who claims divinity or utters falsehoods and lies about Allah, pp. 370-371; bold emphasis mine)
Notice carefully the statement of the Qadi that to assert oneself as the truth is tantamount to making oneself out to be God incarnate. Note further that stating to be able to bring the dead to life is also akin to attributing divinity to oneself.
This is because the Quran expressly states that Allah brings the dead to life since he is al-Baith (“the Resurrector”) and al-Hayy (“the Living One”):
Al-Hayy: The Living
Ever-Living, i.e. Deathless.
Al-Hayy is one of the Ninety-Nine Names.
“Allah, there is no god but Him, the Living, the Self-Sustaining.” (2:253)
“Put your trust in the Living who does not die and glorify Him with praise.” (25:58)…
Al-Bâ’ith: The Raiser
The Raiser, Resurrector. To re-create, like Mu’id; revive; also to send. The One who Quickens mankind after death. To cause something to be.
Al-Ba’ith is one of the Ninety-Nine Names.
“Allah will raise up all those in the graves.” (22:7) (Bewley; bold emphasis mine)
Here’s where the problem lay for Muslims. The Gospels record Jesus as ascribing these very titles and functions to himself.
For instance, Christ called himself the Truth, as well as the Resurrection and the Life who shall raise all the dead from their graves at the hour, on the last day:
“For as the Father raises the dead and gives life to them, even so the Son gives life to whom He will… Most assuredly, I say to you, the hour is coming, and now is, when the dead will hear THE VOICE OF THE SON OF GOD; and those who hear will live. For as the Father has life in Himself, so He has granted the Son to have life in Himself… Do not marvel at this; for the hour is coming in which all who are in the graves will hear HIS [the Son’s] VOICE and come forth—those who have done good, to the resurrection of life, and those who have done evil, to the resurrection of condemnation.” John 5:21, 25-26, 28-29 New King James Version (NKJV)
“‘All that the Father gives Me will come to Me, and the one who comes to Me I will by no means cast out. For I have come down from heaven, not to do My own will, but the will of Him who sent Me. This is the will of the Father who sent Me, that of all He has given Me I should lose nothing, but should raise it up at the last day. And this is the will of Him who sent Me, that everyone who sees the Son and believes in Him may have everlasting life; and I will raise him up at the last day.’ The Jews then complained about Him, because He said, ‘I am the bread which came down from heaven.’ And they said, ‘Is not this Jesus, the son of Joseph, whose father and mother we know? How is it then that He says, “I have come down from heaven”?’ Jesus therefore answered and said to them, ‘Do not murmur among yourselves. No one can come to Me unless the Father who sent Me draws him; and I will raise him up at the last day… Whoever eats My flesh and drinks My blood has eternal life, and I will raise him up at the last day. Read full chapter John 6:37-44, 54 NKJV
“Jesus said to her, ‘Your brother will rise again.’ Martha said to Him, ‘I know that he will rise again in the resurrection at the last day.’ Jesus said to her, ‘I am the resurrection and the life. He who believes in Me, though he may die, he shall live. And whoever lives and believes in Me shall never die. Do you believe this?’ She said to Him, ‘Yes, Lord, I believe that You are the Christ, the Son of God, who is to come into the world.’” John 11:23-27 NKJV
“Jesus said to him, ‘I am the way, the truth, and the life. No one comes to the Father except through Me.’” John 14:6 NKJV
The risen Jesus even went as far as to describe himself as the First and the Last, that very Living One who lives forever and ever,
“And when I saw Him, I fell at His feet as dead. But He laid His right hand on me, saying to me, ‘Do not be afraid; I am the First and the Last. I am He who lives, and was dead, and behold, I am alive forevermore. Amen. And I have the keys of Hades and of Death.’” Revelation 1:17-18 NKJV
Which are also said to be the unique names of Allah!
Al-Awwal, Al-Akhir: The First and the Last
Al-Akhir is He who remains after all His creatures have perished.
Al-Awwal is the First, preceding all others.
Al-Awwal and Al-Akhir are two of the Ninety-Nine Names.
“He is the First and the Last and the Outward and the Inward.” (57:3)
The Prophet said, “…Allah, You are the First, for there was nothing before You, and You are the Last, for there is nothing after You, and you are the Outward, for there is nothing above You, and You are the Inward, for there is nothing beyond You. Remove our debt, and relieve us from poverty.” (Bewley; bold emphasis mine)
This means that, as far as Islamic theology is concerned, the historical Jesus did indeed proclaim himself to be God Almighty in the flesh, being one in essence with the Father and the Holy Spirit. There’s simply no way around this fact.
Therefore, Muslims you have a serious problem since the words of the historical Jesus condemn Muhammad as a false prophet and antichrist for denying that Christ is his very Lord God and Judge.
