A Hadith That’s Always Confused Me – Can Someone Explain?

Al-Nu’man ibn Bashir (may Allah be pleased with him) shared that the Prophet (peace and blessings be upon him) said, “What’s halal is plain, and what’s haram is plain, but in between are things that are doubtful and many people don’t know about them. Whoever stays away from those unclear matters protects their deen and honor. But whoever gets involved in them might end up doing haram, just like a shepherd who lets his flock graze near a private pasture – they’re bound to wander in. Every king has a sanctuary, and Allah’s sanctuary is His prohibitions. And there’s a piece of flesh in the body: if it’s healthy, the whole body is healthy; if it’s rotten, the whole body is rotten – that’s the heart.” (Bukhari and Muslim) I get that generally everything is halal unless there’s proof it’s not, but this hadith makes me feel the opposite sometimes. Like, when scholars disagree on whether something is halal or haram, shouldn’t we just treat it as haram to be safe, based on this hadith? I’d really appreciate some insight, in sha’ Allah.
