Official Catholic statements basically ignore the Koran. For example, the documents of Vatican II quote the Bible a few thousand times and the Koran not at all. Same for the Catechism of the Catholic Church. The Koran doesn't rate. The Bible does.At least in official Catholic statements.
I think you wanted to know about Pope Francis and the Koran though. I found this:
And that pope Francis said "The Koran and the Holy Bible are the same."
That's crazy pope Francis. Except in this case it's not. It's fake news traced back to the National report (
Pope Francis To Followers: "Koran And Holy Bible Are The Same") and has been taken up by other gullible news sites. Snopes lists it as fake here:
FALSE: Pope Francis to Followers: “Koran and Holy Bible Are the Same” and Right Wing Watch list it as fake here:
Drudge Report Falls For Fake Story About ‘Antichrist’ Pope Merging Islam And Christianity | Right Wing Watch
Lots of people got suckered in by this. The Drudge Report and the Christian Post got snookered. It's probably still spreading.
As to whatever the pope may actually think about the Koran? It seems almost impossible to find because it is overwhelmed by this fake news story. But I did find something else interesting. Apparently the pope said "The Koran is a book of peace." Except what he really said, not how it was reported, is that 'Muslims claim the Koran is a book of peace." Rather different. Pope Francis not very careful when speaking. He puts his foot in his mouth regularly. But on this one he was misquoted. And that's real common too. Some journalists are sloppy and others have an agenda. Don't trust what they say the pope said. And if Francis did say something crazy, like he tends to do when speaking off-the-cuff, discount that too.
