Sayyiduna Ammar bin Yasir (may Allah be pleased with him) narrates from the Messenger of Allah (peace and blessings be upon him) that he (peace and blessings be upon him) said: "The lawful is clear and the unlawful is clear, and between the two are doubtful matters. Whoever guards himself against them remains purer for his religion and his honour, and whoever falls into them (the doubtful matters) is about to fall into the major sins, like the shepherd who grazes (his animals) beside the (royal) sanctuary pasture and is about to fall into it. And indeed every king has a sanctuary, and the sanctuary of Allah is His limits."
This report is narrated from Sayyiduna Ammar (may Allah be pleased with him) only with this chain.
