Halal and haram are clear

Two rulings in one hadith. Externally: stay clear of the grey zone, because the grey zone tends to become the black zone. Internally: the heart is the switchboard for the limbs — fix it and the limbs follow.

Ḥalāl is clear and ḥarām is clear, and between the two are doubtful matters that many people do not know. Whoever guards against the doubtful protects his religion and his honour; whoever falls into the doubtful falls into the ḥarām — like a shepherd grazing near a forbidden pasture, the sheep are about to enter.

The Prophet's image is precise. The shepherd does not need to enter the pasture to lose the sheep — he only needs to graze near its edge. The drift is the danger. Most people who fall into the clearly forbidden did not start there; they started in the doubtful and let the slope take them.

The practical rule the scholars draw out is simple: when in doubt, step back. Not because every doubtful matter is forbidden, but because the heart that practises stepping back from the doubtful builds the muscle to step back from the forbidden. The heart that practises drifting toward the doubtful builds the muscle to drift further.
