Al-Ma'idah' - 5:63

لَوْلاَ يَنْهَاهُمُ الرَّبَّانِيُّونَ وَالأَحْبَارُ عَن قَوْلِهِمُ الإِثْمَ وَأَكْلِهِمُ السُّحْتَ لَبِئْسَ مَا كَانُواْ يَصْنَعُونَ
[5:63]
Why do not the learned men and the doctors of law prohibit them from their speaking of what is sinful and their eating of what is unlawfully acquired? Certainly evil is that which they work.
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.
Why do not the rabbis and the priests forbid their evil-speaking and their devouring of illicit gain? Verily evil is their handiwork.
