So here we see that Moses in the Torah and Old Testament spoke of a Prophet to be sent by God who will fulfill the following profile:

1) Will be like Moses

2) Will be from among the Israelite's "brethren"

3) God will literally put His words into his mouth

4) The foretold Prophet will speak in God's name

1) He will be like Moses

The Prophet Muhammad was indeed similar to that of the Prophet Moses. There were hardly any two Prophets ,who were so much alike as Moses and Muhammad (may peace be upon them). Both were given comprehensive law code of life, both encountered their enemies and were victors in miraculous ways, both were accepted as Prophets/statesmen and both migrated following conspiracies to assassinate them.

Like Moses, Muhammad saw and spoke to God. Like Moses, Muhammad married, fathered children and led his nation. Moses took shelter at Midian, which was later named Yathrib after his father-in-law, Jethro. Muhammad also went to Yathrib, which was renamed Medina; where the first ever Islamic Mosque was built.

2) From among the Israelite's "brethren"

Since all the Jews were present in Sinai, the reference to their brothers clearly means the Arabs whom are the descendants of Ishmael - Ishmael being Isaac's brother. Prophet Isaac, peace be upon him, is the Grandfather of the 12 tribes of Israel (Jacob). Ishmael was Abraham's first born son and heir according to ancient customs. Thus plainly, we see that the awaited Prophet was to come from Arabia.

The Bible refers to the Arabs, the children of Ishmael, as a great nation and tells us that God was with Ishmael as he grew up in the desert of Paran. In Genesis [ 21] God comforted Hagar, Abraham's Egyptian wife, in a dream and told her that her son, Ishmael, will not die of thirst:

"Lift the boy up and take him by the hand, for I will make him into a great nation." [18] Then God opened her eyes and she saw a well of water. So she went and filled the skin with water and gave the boy a drink [19]. God was with the boy as he grew up. He lived in the desert and became an archer [20]. While he was living in the Desert of Paran, his mother got a wife for him from Egypt. [21]" - Old Testament (Tanakh) (Genesis 21:18-21)

According to Genesis 21:21 from the above underlined verse, the wilderness of Paran was the place where Ishmael settled (i.e. Arabia, specifically Mecca).

"And this is the blessing, wherewith Moses the man of God blessed the children of Israel before his death. And he said, The LORD came from Sinai, and rose up from Seir unto them; he shined forth from mount Paran, and he came with ten thousands of saints: from his right hand went a fiery law for them."- Old Testament (Tanakh) (Deuteronomy 33:1-2)

The above verse from Deuteronomy 33:1-2 combines references to Moses, Jesus and Muhammad. It speaks of God (i.e. God's revelation). God knows best.:

*Coming from Sinai: possibly relating to Moses and the Torah.

*Rising from Seir (probably the village of Sa'ir near Jerusalem): possibly relating to Jesus and the Gospel.

*Shining forth from Paran: possibly relating to Muhammad and the Qur'an. (peace be upon them all)

One of the signs of the Prophet to come from Paran (Makkah) is that he will come with "ten thousands of saints" (Deuteronomy 33:2). That was exactly the number of faithful who accompanied Prophet Muhammad to Paran (Makkah) in his victorious, bloodless return to his birthplace to destroy the remaining symbols of idolatry.

Also, Isaiah 42:1-13 speaks of the beloved of God. His elect and messenger whom:

"He shall not fail nor be discouraged, till he have set judgment in the earth: and the isles shall wait for his law." - Old Testament (Tanakh) (Isaiah 42:4)

The later verse 11 from this same chapter connects that mysterious "awaited one" with the descendants of Ke'dar

"Let the desert and its towns raise their voices; let the settlements where Kedar lives rejoice. Let the people of Sela sing for joy; let them shout from the mountaintops" - Old Testament (Tanakh) (Isaiah 42:11)

Who is Ke'dar? According to Genesis 25:13, Ke'dar was the second son of Ishmael and is the ancestor of the Prophet Muhammad.

"These are the names of the sons of Ishmael, named in the order of their birth: Nebaioth, the firstborn of Ishmael; and Kedar, Adbeel, Mibsam," - Old Testament (Tanakh) (Genesis 25:13)

3) God will put His words in his mouth

For twenty-three years, God's words (the Qur'an) were truly put into Muhammad's mouth. He was not the "author" of the Qur'an. The Qur'an was dictated to him by the Angel Gabriel (from God) who asked Muhammad to simply repeat the words of the Qur'an as he heard them. These words were then committed to memory and to writing by those who hear them during Muhammad's life time and under his supervision.

4) The foretold Prophet will speak in Gods name

 All except for one chapter in the Qur'an literally begin with the words "In the name of Allah (God), the Compassionate, the Merciful."

Additionally, David prophesied: "Blessed is he who comes in the name of the Lord" (Psalms 118:26).

Could Prophet Muhammad have been a false Prophet?

Deuteronomy 18:20 lastly warns:

"But a Prophet who presumes to speak in my name anything I have not commanded him to say, or a Prophet who speaks in the name of other gods, must be put to death [20]."

Prophet Muhammad spoke not just a single word, but dictated a whole book in God's name. Yet he did not die, but lived to fulfill his message completely. In fact, the first revelation to the Prophet Muhammad instructed him to do just so:

1. Proclaim! (or Read!) in the name of thy Lord and Cherisher, Who created-

– Qur’an English Translation [96:1-5]

He himself even Literally narrated in the name of God a similar verse in the Qur'an giving a similar warning to that of Deuteronomy 18:20:

"And if he (Muhammad) had invented false sayings in Our (God's) name, We would have taken him by the right, then We would have severed from him his aorta, and there is none among you who could have held Us off from him"  – Qur’an English Translation [69:46]

(Remember that the plural form of this verse where you see "We" is the Arabic plural of respect, not the Christian plural of "Trinity").

If the claims of some are true: That Prophet Muhammad was an impostor, then did God go to sleep for twenty three years? Of course not! He knew full well what Muhammad was claiming. If he was not telling the truth, why did God not kill him? Why did he allow him to perpetrate a lie that would span fourteen centuries, and eventually come to cover the entire globe?

Prophet Muhammad's actual name in the Hebrew Tanakh Bible

Furthermore, the Prophet Muhammad is actually mentioned by name in the Hebrew Bible or Old Testament:

"His mouth is most sweet: yea, he is altogether lovely. This is my beloved, and this is my friend, O daughters of Jerusalem."- Old Testament (Tanakh) (Solomon 5:16)

In the Hebrew language 'im' is added for respect. Similarly 'im' is added after the name of Prophet Muhammad to make it Muhammadim. In English translation they have even translated the name of Prophet Muhammad as "altogether lovely", but in the Old Testament in Hebrew, the name of Prophet Muhammad is yet present.

Prophecy from the New Testament

John 16 indicates Jesus (peace be upon him) predicted a counselor to follow him and bring the massage of God to Christians:

"But I tell you the truth: It is for your good that I am going away. Unless I go away, the Counselor will not come to you; but if I go, I will send him to you. When he comes, he will convict the world of guilt in regard to sin and righteousness and judgment in regard to sin, because men do not believe in me; in regard to righteousness, because I am going to the Father, where you can see me no longer; and in regard to judgment, because the prince of this world now stands condemned. I have much more to say to you, more than you can now bear.

But when he, the Spirit of truth, comes, he will guide you into all truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come. He will bring glory to me by taking from what is mine and making it known to you. All that belongs to the Father is mine. That is why I said the Spirit will take from what is mine and make it known to you."  - New Testament (John 16:7-15)

Jesus here foretells  the "spirit of truth" as coming. Muhammad was given the epithet Al-Ameen (or Amin), meaning the Trustworthy, by his kinsmen long before his commission by God. They gave him this title because they considered him to be the best man among them, one who was never known to have told a lie; in essence he exemplified the spirit of truth.

Also, from verse 13, Jesus states that this "spirit of truth" will not speak on his own: he will speak only what he hears. Again, the Qur'an was dictated to him by the Angel Gabriel who asked Muhammad to simply repeat the words of the Qur'an as he heard them.

Also possible, Angel Gabriel is described as the spirit of faith and truth in the Qur'an. The Angel Gabriel transmitted to Muhammad exactly what he was told by God.

"Verily this is a Revelation from the Lord of the Worlds: With it came down the spirit of Faith and Truth- To thy heart and mind, that thou mayest admonish. In the perspicuous Arabic tongue." - Qur’an English Translation [26:192-195]

Jesus speaking of the Prophet to come in the Bible is right in line with what the Qur'an says:

"when Jesus, son of Mary said: '0 children of Israel: Lo! I am the messenger of Allah ‘God’ unto you, confirming that which was (revealed) before me in the Torah, and bringing good tidings of a messenger who will come after me, whose name is praised one.' Yet when he has come unto them with clear proofs, they say: This is mere magic." – Qur’an English Translation [61:6]
