The Prophet ﷺ once said:

"The Halal is clear and the Haram is clear, but between them are doubtful matters which many people do not know. Whoever avoids the doubtful matters protects his deen and his honor. But whoever falls into the doubtful matters is like a shepherd grazing near the boundary of forbidden land — soon he will cross into it."

Right and wrong are obvious. But in between lies a vast grey area - things that are technically permissible but spiritually risky, things that seem acceptable but erode your character slowly.
