The Koran teaches nothing like that. It teaches not to associate with non-muslims.

2 Corinthians 6:14 ESV
Do not be unequally yoked with unbelievers. For what partnership has righteousness with lawlessness? Or what fellowship has light with darkness?

1 Corinthians 5:11 ESV
But now I am writing to you not to associate with anyone who bears the name of brother if he is guilty of sexual immorality or greed, or is an idolater, reviler, drunkard, or swindler—not even to eat with such a one.
Ezekiel 33:9 ESV
But if you warn the wicked to turn from his way, and he does not turn from his way, that person shall die in his iniquity, but you will have delivered your soul.
Romans 12:2 ESV
Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.
Galatians 6:10 ESV
So then, as we have opportunity, let us do good to everyone, and especially to those who are of the household of faith.
Colossians 4:5-6 ESV
Walk in wisdom toward outsiders, making the best use of the time. Let your speech always be gracious, seasoned with salt, so that you may know how you ought to answer each person.
1 Corinthians 5:9-13 ESV
I wrote to you in my letter not to associate with sexually immoral people— not at all meaning the sexually immoral of this world, or the greedy and swindlers, or idolaters, since then you would need to go out of the world. But now I am writing to you not to associate with anyone who bears the name of brother if he is guilty of sexual immorality or greed, or is an idolater, reviler, drunkard, or swindler—not even to eat with such a one. For what have I to do with judging outsiders? Is it not those inside the church whom you are to judge? God judges those outside. “Purge the evil person from among you.”
Mark 16:16 ESV
Whoever believes and is baptized will be saved, but whoever does not believe will be condemned.
Romans 8:7 ESV
For the mind that is set on the flesh is hostile to God, for it does not submit to God's law; indeed, it cannot.

As I wrote above, Islam, Judaism, and Christianity are all Abrahamic religions with the same poems and same God. If you condemn one, you condemn ALL THREE.
...because if you chose to only condemn one, you're being intellectually dishonest.
