Gen 16:11 And the angel of the LORD said unto her, Behold, thou art with child, and shalt bear a son, and shalt call his name Ishmael; because the LORD hath heard thy affliction.
Gen 16:12 And he will be a wild man; his hand will be against every man, and every man's hand against him; and he shall dwell in the presence of all his brethren.
Do you believe in coincidence? I don’t! By the time Muhammad received his first “visitation” in 610 A.D., the Roman Empire, including the entire Middle East and North Africa, had been “peacefully” converted to Christianity. Christians were also rapidly spreading the gospel into Africa, Persia, and the Russian steps.
Muhammad was well acquainted with Christianity and exerted quite a bit of energy trying to convince Christians and Jews that he was a prophet. At first, his “revelations” from Allah appeared to be an attempt to convince Jews, Christians, and Muslims that they were all on the same team.
VERILY, those who have attained to faith [in this divine writ], as well as those who follow the Jewish faith, and the Christians, and the Sabians  -all who believe in God and the Last Day and do righteous deeds-shall have their reward with their Sustainer; and no fear need they have, and neither shall they grieve.  - 2:62 (Asad)
However, as Muhammad realized his attempts to convert Jews and Christians to Islam would not be successful, his “revelations” became progressively more and more antagonistic toward “Jews, Christians, and the fundamental teachings of the Church”.
O YOU who have attained to faith! Do not take the Jews and the Christians for your allies: they are but allies of one another  and whoever of you allies himself with them becomes, verily, one of them; behold, God does not guide such evildoers.  - 5:51 (Asad)
Eventually, Muhammad directly contradicted the basic teachings of the New Testament. First, he denied that Jesus Christ is the Son of God.
AND THE JEWS say, "Ezra is God's son," while the Christians say, "The Christ is God's son." Such are the sayings which they utter with their mouths, following in spirit assertions made in earlier times by people who denied the truth!  [They deserve the imprecation:] "May God destroy them!"  How perverted are their minds!  - 9:30
The Apostle John made it clear that anyone denying the Son is a liar and an antichrist.
1Jn 2:21 I have not written unto you because ye know not the truth, but because ye know it, and that no lie is of the truth.
1Jn 2:22 Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son.
1Jn 2:23 Whosoever denieth the Son, the same hath not the Father: (but) he that acknowledgeth the Son hath the Father also.
Second, Muhammad denied the death and resurrection of Jesus Christ.
Quran (Pickthall): An-Nisa' (The Women): 157 And because of their saying: We slew the Messiah, Jesus son of Mary, Allah's messenger - they slew him not nor crucified him, but it appeared so unto them; and lo! those who disagree concerning it are in doubt thereof; they have no knowledge thereof save pursuit of a conjecture; they slew him not for certain.
Third, Muhammad denied the truth of holy scripture.
Hadith (Bukhari): Volume 9, Book 92, Number 461: Narrated Ubaidullah: Ibn 'Abbas said, "Why do you ask the people of the scripture about anything while your Book (Quran) which has been revealed to Allah's Apostle is newer and the latest? You read it pure, undistorted and unchanged, and Allah has told you that the people of the scripture (Jews and Christians) changed their scripture and distorted it, and wrote the scripture with their own hands and said, 'It is from Allah,' to sell it for a little gain. Does not the knowledge which has come to you prevent you from asking them about anything? No, by Allah, we have never seen any man from them asking you regarding what has been revealed to you!"
Finally, towards the end of his life, Muhammad began to preach a doctrine of intolerance and violence towards Jews and Christians.
Hadith (Muslim): Book 019, Number 4366: It has been narrated by 'Umar b. al-Khattib that he heard the Messenger of Allah (may peace be upon him) say: I will expel the Jews and Christians from the Arabian Peninsula and will not leave any but Muslim.
(30) Narrated 'Abdullah bin 'Umar: Allah's Apostle said, "You (i.e. Muslims) will fight with the Jews till some of them will hide behind stones. The stones will (betray them) saying, 'O 'Abdullah (i.e. slave of Allah)! There is a Jew hiding behind me; so kill him.' " (Book #52, Hadith #176)
The same homicidal spirit that motivated Haman to kill all the Jews in Persia also took possession of Muhammad. He also began to include Christians in Allah’s invectives and curses.
Hadith (Muslim): Book 001, Number 0284: It is narrated on the authority of Abu Huraira that the Messenger of Allah (may peace be upon him) observed: By Him in Whose hand is the life of Muhammad, he who amongst the community of Jews or Christians hears about me, but does not affirm his belief in that with which I have been sent and dies in this state (of disbelief), he shall be but one of the denizens of Hell-Fire.
Hadith (Malik): Book 45, Number 45.5.17: Yahya related to me from Malik from Ismail ibn Abi Hakim that he heard Umar ibn Abd al-Aziz say, "One of the last things that the Messenger of Allah, may Allah bless him and grant him peace, said was, 'May Allah fight the Jews and the Christians. They took the graves of their Prophets as places of prostration."
Although the Arabs were mainly following their ancient pagan religions prior to Muhammad, by the time Muhammad began receiving his “revelations” from Allah, Christianity was rapidly spreading through the various Arabic tribes. Therefore, Christianity was the primary competition to the new religion of Islam.
Christian doctrine came to Arabia from the North, from Syria and Babylonia, and numerous conversions, for the most part of whole tribes, were made. On the frontiers also Arabian merchants came into continual contact with Christianity and foreign merchants of the Christian faith could be found throughout Arabia. But for the Arabian migration and the simultaneous foundation of a new Arabian religion, there is no doubt that the whole peninsula would have been speedily converted to Christianity. Christianity and Islam, by C.H. Becker, 1909.
I firmly believe that Muhammad did receive a visitation from an angel, but I am also firmly convinced that the angel was NOT Gabriel.
2Co 11:14 And no marvel; for Satan himself is transformed into an angel of light.
2Co 11:15 Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works.
We can know where a person is receiving their “revelations” from by their WORKS! We simply need to ask the following question: Is a minister producing the fruits of the spirit or the fruits of the flesh? Muhammad personally killed hundreds of Jewish men, who had surrendered themselves into his power. Muhammad took a Jewish concubine, who later died in his power. Muhammad and his followers robbed and plundered caravans and towns. Muhammad received “revelations” that directly contradicted the Word of God in the New Testament. These are NOT the works of a minister of righteousness.
Within one hundred years of Muhammad’s death, his followers had conquered most of the Christian Middle East. The areas of Egypt, Syria, and Iraq required a very complex administration of vast agricultural areas. It would have been impossible for the Muslims to administer these complex administrative systems without the help of educated Christian administrators. Also, many nominal Christians became apostates in order to secure their government positions with their new Islamic rulers. I expect the same thing will happen when nominal Christians are faced with a worldwide antichrist government.
Of primary importance was the fact that both Christians and Jews, and the former in particular, accepted Islam by thousands, and formed a new intellectual class of ability infinitely superior to that of the original Muslims and able to attract the best elements of the Arab nationality to their teaching. It was as impossible for these apostate Christians to abandon their old habits of thought as it was hopeless to expect any sudden change in the economic conditions under which they lived. Christianity and Islam, by C.H. Becker, 1909.
Within two hundred years of Muhammad’s death, Northern Africa and most of Spain had also fallen to the Muslim Sword. For over one thousand years Christian lands were under constant attack by Muslim armies. In 1453, the Eastern Orthodox City of Constantinople was captured by the Ottoman Turks and the largest Church in the world, the Hagia Sophia, was converted into the largest Mosque in the world. Finally, in 1683 at the gates of Vienna, the Ottoman Turks’ army of approximately 170,000 men was turned back from invading Europe by the combined armies of the Habsburg Monarchy, the Polish-Lithuanian Commonwealth, and the Holy Roman Empire.
The Battle of Vienna (German: Schlacht am Kahlen Berge or Kahlenberg; Polish: bitwa pod Wiedniem or odsiecz wiedeńska (The Relief of Vienna); Modern Turkish: İkinci Viyana Kuşatması, Ottoman Turkish: Beç Ḳalʿası Muḥāṣarası) took place at Kahlenberg Mountain near Vienna on 12 September 1683 after the imperial city had been besieged by the Ottoman Empire for two months. The battle was fought by the Habsburg Monarchy, the Polish-Lithuanian Commonwealth and the Holy Roman Empire, under the command of King John III Sobieski against the invading Muslim Ottoman Empire and its vassal and tributary states. The battle marked the first time the Commonwealth and the Holy Roman Empire had cooperated militarily against the Ottomans, and it is often seen as a turning point in history, after which "the Ottoman Turks ceased to be a menace to the Christian world". In the ensuing war that lasted until 1699, the Ottomans lost almost all of Hungary to the Holy Roman Emperor Leopold I. https://en.wikipedia.org/wiki/Battle_of_Vienna
Currently, the Babylonian rulers of Europe are throwing open the doors to millions of Muslim “refugees”. I do not believe this is an accident. There is a definite Satanic agenda to destroy Christianity in Europe. For the last 1400 years, the religion of Islam has been one of the major instruments by the powers of darkness to prevent the spread of the gospel around the world. In many Islamic nations it is still a crime to preach the gospel to Muslims, and Christians face deportation, jail, and even death. The most common form of capital punishment in Islamic countries is cutting off the head. Beheading is the form of capital punishment encouraged by Muhammad, and is still common today in many Muslim countries. Therefore, I believe Islam will play a major role in end times prophecy.
Rev 20:4 And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
