An-Nu'man ibn Basheer reported: I heard the Messenger of Allah, peace and blessings be upon him, say, "Verily, the lawful is clear and the unlawful is clear, and between the two of them are doubtful matters about which many people do not know. Thus, he who avoids doubtful matters clears himself in regard to his religion and his honor, and he who falls into doubtful matters will fall into the unlawful as the shepherd who pastures near a sanctuary, all but grazing therein. Verily, every king has a sanctuary and the sanctuary of Allah is His prohibitions. Verily, in the body there is a piece of flesh which if upright then the entire body is upright, and if corrupt then the entire body is corrupt. No doubt it is the heart."

Give up what appears to be doubtful for what is certain.
Truth brings peace of mind, and deception doubt.
