The lawful, the unlawful and the doubtful

On the authority of Abū ʿAbd Allāh al-Nuʿmān ibn Bashīr, may Allah be pleased with them both, who said: I heard the Messenger of Allah ﷺ say: The lawful is clear and the unlawful is clear, and between them are doubtful matters which many people do not know. So whoever guards against the doubtful has kept his religion and his honour clear, and whoever falls into the doubtful falls into the unlawful, like a shepherd who grazes around a protected pasture and is about to graze within it. Indeed every king has a protected pasture, and indeed the protected pasture of Allah is what He has forbidden. Indeed in the body there is a lump of flesh: when it is sound the whole body is sound, and when it is corrupt the whole body is corrupt. Indeed it is the heart.
