Surah Al-Mai'dah (The Spread Table), Verse 63

لَوْلَا یَنْهٰىهُمُ الرَّبّٰنِیُّوْنَ وَالْاَحْبَارُ عَنْ قَوْلِهِمُ الْاِثْمَ وَاَكْلِهِمُ السُّحْتَ لَبِئْسَ مَا كَانُوْا یَصْنَعُوْنَ ۟

Law laa yanhaahumur rabbaaniyyoona wal ahbaaru 'an qawlihimul ismaa wa aklihimus suht; labi'sa maa kaanoo yasna'oon

“Why do not the rabbis and the doctors of Law forbid them from their (habit of) uttering sinful words and eating things forbidden? Evil indeed are their works.”
