Surah Al-An'am, ayah 121

6:121

وَلَا تَأۡكُلُواْ مِمَّا لَمۡ يُذۡكَرِ ٱسۡمُ ٱللَّهِ عَلَيۡهِ وَإِنَّهُۥ لَفِسۡقٞۗ وَإِنَّ ٱلشَّيَٰطِينَ لَيُوحُونَ إِلَىٰٓ أَوۡلِيَآئِهِمۡ لِيُجَٰدِلُوكُمۡۖ وَإِنۡ أَطَعۡتُمُوهُمۡ إِنَّكُمۡ لَمُشۡرِكُونَ ١٢١

Walā ta'kulū mimmā lam yudhkarismullāhi 'alayhi wa innahū lafisqun wa innash-shayātīna layūhūna ilā awliyā'ihim liyujādilūkum wa in ata'tumūhum innakum lamushrikūn

And do not eat of that upon which the name of Allāh has not been mentioned, for indeed, it is grave disobedience. And indeed do the devils inspire their allies [among men] to dispute with you. And if you were to obey them, indeed, you would be associators [of others with Him].341
