Nu'man bin Bashir (RA) reported: I heard Allah's Messenger (may peace be upon himn) as having said this (and Nu'man) pointed towards his ears with his fingers): What is lawful is evident and what is unlawful is evident, and in between them are the things doubtful which many people do not know. So he who guards against doubtful things keeps his religion and honour blameless, and he who indulges in doubtful things indulges in fact in unlawful things, just as a shepherd who pastures his animals round a preserve will soon pasture them in it. Beware, every king has a preserve, and the things God his declaced unlawful are His preserves. Beware, in the body there is a piece of flesh; if it is sound, the whole body is sound and if it is corrupt the whole body is corrupt, and hearken it is the heart.

This hadith has been narrated on the authority of Zakariya with the same chain of transmitters.

AI-Nu'man bin Bashir reported it from Allah's Apostle ( صلی اللہ علیہ وسلم ) . The hadith narrated by Zakariya is, however, more complete and lengthy than the other ones.

Nu'man bin Bashir bin Sa'd, a Companion of Allah's Messenger ( صلی اللہ علیہ وسلم ) was heard delivering a sermon at Hims and was saying: I heard Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: The lawful is evident and the unlawful is evident, the rest of the hadith is the same as related by Zakariya.
