How do we know who truly interprets the Quran correctly?

By: u/LogicalAwareness9361

The salafis, sunnis, Shias, ahmaddiyahs, the Quranists.

The Quran argues against using the Quran to fit your nafs and desires but arguably every single person is somewhat biased based on their upbringing, own moral code etc - so who’s to say what is based on their own nafs and what is truly the Qurans message?

The salafis argue that progressives use their nafs, the progressives say it’s the salafis. The sunnis say it’s Shias, the Shias say it’s Sunnis.

So how do we know?

Note: I’m speaking in broad terms only for simplicity - I know not every member of these groups truly believe every other is corrupt etc
