“Muhammad fancied himself a Prophet like Jesus and the Prophets of the Old Testament. The problem with Muhammad's claim is that a Prophet must give prophecies (detailed predictions of future events which must come true) in order to be called a Prophet. One does not bestow the title on himself as Muhammad did. Muhammad failed the Bible's test and, therefore, cannot be considered a Prophet” (Andrew Vargo,

"When a prophet speaks in the Name of the Lord, if the word does not come to pass or come true, that is a word which the Lord has not spoken, the prophet has spoken it presumptuously, you need not be afraid of him.".(Deuteronomy 18:21-22)
Prophecies of Muhammad(pbuh)
‘Umar reports in a narration recorded in Sahih al-Muslim:
‘Before the Battle of Badr started, God’s Messenger, upon him be peace and blessings, walked around the battlefield and pointed to some locations, saying, Abu Jahl will be killed here, ‘Utba here, Shayba here, Walid here, and so on. By God, we found, after the battle, the dead bodies of all those men in the exact places that God’s Messenger had pointed out.’
Bukhari, Muslim and Ahmad ibn Hanbal record:
During the construction of the Prophet’s Mosque in Madina, God’s Messenger, upon him be peace and blessings, told ‘Ammar:
What a pity O ‘Ammar, a rebellious group will kill you.
‘Ammar was killed in the Battle of Siffin by the supporters of Mu‘awiya, who rebelled against Caliph ‘Ali.
The Prophet, upon him be peace and blessings, predicted the Mongol invasion, saying:
The Hour will not come before you fight against a people with red faces, small, slant eyes and flat noses. They wear hairy leather boots.
According to an authentic narration, the Prophet, upon him be peace and blessings, declared:
‘Uthman will be killed while reading the Qur’an. God will dress him in a shirt but they will desire to remove it from him.
By this saying, he meant that ‘Uthman would become Caliph but his deposition would be sought, and finally he would be martyred while reading the Qur’an. This happened exactly as he predicted.
Again, according to an authentic narration, the Prophet, upon him be peace and blessings, declared:
Surely, Constantinople (Istanbul) will be conquered (by my community); how blessed the commander who will conquer it, and how blessed his army.
Ali ibn Abi Talib, the fourth Caliph, had also been informed by the Prophet of his assassination in such detail that he knew the man who was going to kill him, and identified him pointing him out to the people. They asked Ali why he did not kill the man and he replied: "Then who will kill me?" The night preceding his assassination Ali came out, gazed at the sky and said: "By Allah the prophet (peace be upon him) never told a lie, nor was a lie ever told to him." The next day the same man killed Ali, as the prophet had predicted.
