Surah Al-Ma'idah, Verse 63

لَوۡلَا يَنۡهَىٰهُمُ ٱلرَّبَّٰنِيُّونَ وَٱلۡأَحۡبَارُ عَن قَوۡلِهِمُ ٱلۡإِثۡمَ وَأَكۡلِهِمُ ٱلسُّحۡتَۚ لَبِئۡسَ مَا كَانُواْ يَصۡنَعُونَ٦٣

lawlā yanhāhumu l-rabāniyūna wal-aḥbāru ʿan qawlihimu l-ith'ma wa-aklihimu l-suḥ'ta labi'sa mā kānū yaṣnaʿūna

Why do the rabbis and religious scholars not forbid them from saying what is sinful and devouring what is unlawful? How wretched is what they have been practicing.
