In Surah Al Baqarah verse 2 it says “this is the book of which there is no doubt a guidance for those conscious of Allah.” The Quran is a book of guidance.
The Quran has always been a book of guidance and will always be a book of guidance. On any page in the Quran, there is some form of guidance or teaching. This teaching has benefits for human beings if implemented correctly.
Try it for yourself. Open up any page of the Quran and somewhere on that page you will find some form of guidance.
