Contradicting the Quran
The Qur'an commands Muslims to believe in the revelations given to all of God's prophets. These prophets include Moses, David, and Jesus (peace be upon them). Muslims must believe in the revelations received by such prophets. Books associated with them are called by the names Torah, Psalms, and Gospel.
Muhammad in the Old Testament?
Arguments that prophecies of Muhammad in the Bible presaged his birth, teachings, and death have formed part of Muslim tradition from the early history of Muhammad's Ummah. Subsequent Muslim writers have expanded on these viewpoints and have argued that they can specifically identify references to Muhammad in the text of the Bible, being found both in the Jewish Tanakh and in the Christian New Testament.
Those who follow the Messenger, the unlettered prophet, whom they find written in what they have of the Torah and the Gospel, who enjoins upon them what is right and forbids them what is wrong and makes lawful for them the good things and prohibits for them the evil and relieves them of their burden and the shackles which were upon them. So they who have believed in him, honored him, supported him and followed the light which was sent down with him - it is those who will be the successful.
I shall raise up for them a Prophet like you out of the midst of their brothers. And I shall put My Words in His mouth, and He shall speak to them all that I command Him.
And beginning at Mosheh and all the Prophets, He was explaining to them in all the Scriptures the matters concerning Himself.
The Christians say that this prophecy refers to Jesus (pbuh) because Jesus (pbuh) was like Moses (pbuh). Moses (pbuh) was a Jew, as well as Jesus (pbuh) was a Jew. Moses (pbuh) was a Prophet and Jesus (pbuh) was also a Prophet. If these two are the only criteria for this prophecy to be fulfilled, then all the Prophets of the Bible who came after Moses (pbuh) such as Solomon, Isaiah, Ezekiel, Daniel, Hosea, Joel, Malachi, John the Baptist, etc. (pbut) will fulfill this prophecy since all were Jews as well as prophets. ...
It is Mentioned in the book of Deuteronomy chapter 18:19. "And it shall come to pass, that whosoever will not harken unto my words which he shall speak in my name, I will require it of him."
YHWH your Elohim shall raise up for you a Prophet like me from your midst, from your brothers. Listen to Him, according to all you asked of YHWH your Elohim in Horeb in the day of the assembly, saying, ‘Let me not hear again the voice of YHWH my Elohim, nor let me see this great fire any more, lest I die.’ “And YHWH said to me, ‘What they have spoken is good. I shall raise up for them a Prophet like you out of the midst of their brothers. And I shall put My Words in His mouth, and He shall speak to them all that I command Him. And it shall be, the man who does not listen to My Words which He speaks in My Name, I require it of him.
Arnold Friberg - The Ten Commandments
and that He sends YHWSO Messiah, pre-appointed for you, whom heaven needs to receive until the times of restoration of all matters, of which Elohim spoke through the mouth of all His set-apart prophets since of old. "For Mosheh truly said to the fathers, 'YHWH your Elohim shall raise up for you a Prophet like me from your brothers. Him you shall hear according to all matters, whatever He says to you. 'And it shall be that every being who does not hear that Prophet shall be utterly destroyed from among the people.' "And likewise, all the prophets who have spoken, from Shemu'el and those following, have also announced these days.
It is mentioned in the book of Isaiah chapter 29 verse 12: "And the book is delivered to him that is not learned, saying, Read this, I pray thee: and he saith, I am not learned." When Archangel Gabrail commanded Muhammad (pbuh) by saying Iqra - "Read", he replied, "I am not learned".
Isaiah 29 is a chapter of announcing punishment on Israel. ... and as part of the punishment we read that God will also take away the ability to read (understand) the holy word because they have disobeyed it for so long.
Prophet Muhammad (pbuh) is mentioned by name in the Song of Solomon chapter 5 verse 16: "Hikko Mamittakim we kullo Muhammadim Zehdoodeh wa Zehraee Bayna Jerusalem."
His mouth is most sweet, And he is altogether lovely. This is my beloved, and this is my friend, O daughters of Yerushalayim!
Muhammad in the New Testament?
And [mention] when Jesus, the son of Mary, said, "O children of Israel, indeed I am the messenger of Allah to you confirming what came before me of the Torah and bringing good tidings of a messenger to come after me, whose name is Ahmad." But when he came to them with clear evidences, they said, "This is obvious magic."
John chapter 14 verse 16: "And I will pray the Father, and he shall give you another Comforter, that he may abide with you forever." ... The Sprit of Truth, spoken about in this prophecy referes to none other than Prophet Muhammad (pbuh)
And I shall ask the Father, and He shall give you another Helper, to stay with you forever — the Spirit of the Truth, whom the world is unable to receive, because it does not see Him or know Him. But you know Him, for He stays with you and shall be in you. ... [and later on in verse 26] ... But the Helper, the Set-apart Spirit, whom the Father shall send in My Name, He shall teach you all, and remind you of all that I said to you.
Then YHWSO said to them again, "Peace to you! As the Father has sent Me, I also send you." And having said this, He breathed on them, and said to them, "Receive the Set-apart Spirit.
The first account I made, O Theophilos, of all that YHWSO began both to do and to teach, until the day when He was taken up, after giving instructions through the Set-apart Spirit to the emissaries whom He had chosen, to whom He also presented Himself alive after His suffering by many infallible proofs, being seen by them for forty days, speaking concerning the reign of Elohim.
Muhammad the false prophet
YHWSO said to him, "I am the Way, and the Truth, and the Life. No one comes to the Father except through Me.
"But beware of the false prophets, who come to you in sheep's clothing, but inwardly they are savage wolves. "By their fruits you shall know them. Are grapes gathered from thornbushes or figs from thistles?
Every Word of Eloah is tried; He is a shield to those taking refuge in Him. Do not add to His Words, Lest He reprove you, and you be found a liar.
"Do not think that I came to destroy the Torah or the Prophets. I did not come to destroy but to complete.
Son of God
Islam completely denies that Jesus was the begotten son of God...
O People of the Scripture, do not commit excess in your religion or say about Allah except the truth. The Messiah, Jesus, the son of Mary, was but a messenger of Allah and His word which He directed to Mary and a soul [created at a command] from Him. So believe in Allah and His messengers. And do not say, "Three"; desist - it is better for you. Indeed, Allah is but one God. Exalted is He above having a son. To Him belongs whatever is in the heavens and whatever is on the earth. And sufficient is Allah as Disposer of affairs.
And having been immersed, YHWSO went up immediately from the water, and see, the heavens were opened, and He saw the Spirit of Elohim descending like a dove and coming upon Him, and see, a voice out of the heavens, saying, "This is My Son, the Beloved, in whom I delight."
Who is the liar, except the one denying that YHWSO is the Messiah? This is the anti-messiah, the one denying the Father and the Son. No one denying the Son has the Father. The one confessing the Son has the Father as well.
