Quran 6:121 from Surah Al-An'aam on Divine Marvels.
وَلَا تَأۡكُلُواْ مِمَّا لَمۡ يُذۡكَرِ ٱسۡمُ ٱللَّهِ عَلَيۡهِ وَإِنَّهُۥ لَفِسۡقٞۗ وَإِنَّ ٱلشَّيَٰطِينَ لَيُوحُونَ إِلَىٰٓ أَوۡلِيَآئِهِمۡ لِيُجَٰدِلُوكُمۡۖ وَإِنۡ أَطَعۡتُمُوهُمۡ إِنَّكُمۡ لَمُشۡرِكُونَ
English translation: And (do) not eat of that not has been mentioned (the) name (of) Allah on it and indeed, it (is) grave disobedience And indeed the devils inspire to their friends so that they dispute with you and if you obey them indeed, you (would) be the polytheists
Transliteration: wala takulu mimma lam yudh'kari us'mu al-lahi alayhi wa-innahu lafis'qun wa-inna al-shayatina layuhuna ila awliyaihim liyujadilukum wa-in ata'tumuhum innakum lamush'rikuna
