Koran 5:19
O People of the Scripture, there has come to you Our Messenger to make clear to you [the religion] after a period [of suspension] of messengers, lest you say, “There came not to us any bringer of good tidings or a warner.”

And Allāh is over all things competent.

Koran 5:82-84
5:82 You will surely find the most intense of the people in animosity toward the believers [to be] the Jews and those who associate others with Allāh; and you will find the nearest of them in affection to the believers those who say, “We are Christians.”
That is because among them are priests and monks and because they are not arrogant.
83 And when they hear what has been revealed to the Messenger, you see their eyes overflowing with tears because of what they have recognized of the truth.
They say, “Our Lord, we have believed, so register us among the witnesses. 84 And why should we not believe in Allāh and what has come to us of the truth? And we aspire that our Lord will admit us [to Paradise] with the righteous people.”
Koran 5:82-84
Koran 7:157
This verse is clearly about Jesus, not about Muhammad the false prophet.
Those who follow the Messenger, the unlettered prophet, whom they find written [i.e., described] in what they have of the Torah and the Gospel, who enjoins upon them what is right and prohibits them from what is wrong and makes lawful for them what is good and forbids them from what is 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.
Koran 7:157
Koran 9:30
and the Christians say, “The Messiah is the son of Allāh.”
Excerpt, Koran 9:30
Conclusion
The words of Christians are in the Koran, which shows that Muhammad (and his friends) are the source of Muhammad’s Koran, so showing Allah is an idol, and so Islam is false.
