An-Numan bin Bashir said: “I heard the Messenger of Allah صلی اللہ علیہ وآلہ وسلم say: ‘That which is lawful is plain and that which is unlawful is plain, and between them are matters which are not as clear. I will strike a parable for you about that: …indeed Allah, the Mighty and blime, has established a nctuary, and the sanctuary of ah is that which He has rbiddefl. Whoever approaches Le sanctuary is bound to transgress pon it.’ Or he said: ‘Whoever s around the sanctuary will transgress upon it, and indulges in matters that re not clear, he will soon transgress beyond the limits.”
