Musannaf Ibn Abi Shaybah

Hazrat Aamir narrates that I heard Hazrat Nu’man bin Basheer (may Allah be pleased with him) delivering a sermon, in such a state that he had inserted his fingers into his ears. He said: I myself heard from the Prophet Muhammad (peace and blessings be upon him) with these ears, that he said: Halal is clear and haram is clear, and between them are some doubtful matters. Whoever avoids the doubtful matters has protected his religion and honor. And whoever falls into the doubtful matters falls into haram, just like a shepherd who grazes his animals around a sanctuary; soon they will enter it. Beware! Every king has a sanctuary, and Allah’s sanctuary is His prohibited things. Beware! There is a piece of flesh in the body; if it is sound, the whole body is sound, and if it is corrupt, the whole body is corrupt. Listen! That is the heart.
