Anyway, let's get back to the Muhammed.
So Muhammed can make prophecies and they can come true, but he does not know that Christians do not worship three gods, and he does not know that in true Christianity, we do not worship Mary? What kind of a man can prophecy and yet make false claims on a religion? That's like me pointing out all the violent acts of Islam and saying the Qu'ran supports it eventhough you might feel I am taking the Qu'ran out of context. Now how can Muhammed prophecy when he can't even get his facts straight?
And if thou (Muhammad) art in doubt concerning that which We reveal unto thee, then question those who read the Scripture (that was) before thee. Verily the Truth from thy Lord hath come unto thee. So be not thou of the waverers. And be not thou of those who deny the revelations of Allah, for then wert thou of the losers. S. 10:94-95 Pickthall
Right here is what it all comes down to. If we judge by the basis of the scripture before Muhammed, then Muhammed is a false prophet. Scripture before Muhammed says jesus died on the cross. Scripture before Muhammed said if another gospel besides the gospel of Jesus Christ is preached, let that person be cursed. Now you might say that the scripture we have now is corrupt. If the Biblical scripture we have today is corrupt, then that verse which I just posted from the Qu'ran is said in vain.
Now back to the prophecies of Muhammed:
Several problems immediately arise from a plain reading of the text. This alleged prophecy is a great example of how incoherent, incomplete and unintelligible the Quran truly is. The prophecy states that the Romans have been defeated in a land close by. Yet, we are not told who defeated them, when were they defeated, and where were they defeated. Is the phrase a "land close by" directed towards the Muslims or the Romans? If one claims that it refers to the Muslims then this still leaves us with the problem of identifying the precise location of the land. A land close to the Muslims can be a reference to Medina (provided that this was "revealed" during the time the Muslims were still in Mecca), Mecca, Syria, Turkey, Lebanon, Jerusalem, Persia etc. If it is referring to the Romans themselves, then the land close by can refer to a land near either Turkey (Constantinople) or Rome. How does anyone know for certain?
Second, who defeated the Romans and how does one know for certain? Third, when was this "prophecy" given? Is it Pre-Hijrah or post-Hijrah? Since the prophecy states that the Romans would be victorious within a few years, knowing the precise date of this alleged prophecy is an essential and integral part of verifying whether it came to pass or not.
According to Muslim scholarship this passage was supposedly “sent down” approximately around 615 AD and refers to the defeat of the Romans at the hands of the Persians. When we consult the encyclopedias and other sources we discover that the Roman victory didn’t occur until 13 years later, not the 3-9 years stipulated by the Quran. Under Heraclius, Encyclopedia Britannica writes:
In 614 the Persians conquered Syria and Palestine, taking Jerusalem and what was believed to be Christ's Cross, and in 619 occupied Egypt and Libya ...
In 622, clad as a penitent and bearing a sacred image of the Virgin, he left Constantinople, as prayers rose from its many sanctuaries for victory over the Persian Zoroastrians, the recovery of the Cross, and the reconquest of Jerusalem…
The next two years he devoted to campaigns in Armenia, the manpower of which was vital to the empire, and to a devastating invasion of Persia. In 625 Heraclius retired to Anatolia. He had encamped on the west bank of the Sarus River when the Persian forces appeared on the opposite bank. Many of his men rushed impetuously across the bridge and were ambushed and annihilated by the enemy.
Emerging from his tent, Heraclius saw the triumphant Persians crossing the bridge. The fate of the Empire hung in the balance. Seizing his sword, he ran to the bridge and struck down the Persian leader. His soldiers closed rank behind him and beat back the foe.
In 626 the Persians advanced to the Bosporus, hoping to join the Avars in an assault on the land walls of Constantinople. But the Romans sank the primitive Avar fleet that was to transport Persian units across Bosporus and repelled the unsupported Avar assault. Heraclius again invaded Persia and in December 627, after a march across the Armenian highlands into the Tigris plain, met the Persians near the ruins of Nineveh. There, astride his renowned war-horse, he killed three Persian generals in single combat, charged into enemy ranks at the head of his troops, killed the Persian commander, and scattered the Persian host.
A month later, Heraclius entered Dastagird with its stupendous treasure. Khosrow was overthrown by his son, with whom Heraclius made peace, DEMANDING ONLY THE RETURN OF THE CROSS, the captives, AND CONQUERED ROMAN TERRITORY. Returning to Constantinople in triumph, he was hailed as a Moses, an Alexander, a Scipio. IN 630 HE PERSONALLY RESTORED THE CROSS TO THE CHURCH OF THE HOLY SEPULCHRE IN JERUSALEM.
