Stay away from doubtul matters according to God's commands .

This hadith emphasizes the importance of avoiding doubtful things and staying away from what God has declared unlawful. Nu'man b. Bashir reported that he heard Allah's Messenger say that what is lawful is evident and what is unlawful is evident, but in between them are the things doubtful which many people do not know. He then compared it to a shepherd who pastures his animals round a preserve, eventually leading them into it as well if they are not careful enough to stay away from it. The Prophet also warned that every king has a preserve, and the things God has declared unlawful are His preserves too, so one should be careful to stay away from them as well. Finally, he pointed out that just like how the heart can affect the whole body if it becomes corrupt, so too can indulging in doubtful matters lead one astray into committing sins unknowingly or unintentionally.
