Do not eat from that upon which the name of God has not been mentioned, for it is an abomination. The devils inspire their allies to argue with you; if you obey them, you will be idol worshipers.*
وَلا تَأكُلوا مِمّا لَم يُذكَرِ اسمُ اللَّهِ عَلَيهِ وَإِنَّهُ لَفِسقٌ وَإِنَّ الشَّيٰطينَ لَيوحونَ إِلىٰ أَولِيائِهِم لِيُجٰدِلوكُم وَإِن أَطَعتُموهُم إِنَّكُم لَمُشرِكونَ
wa laa ta’kuloo mimmaa lam yuzkaris mullaahi ‘alaihi wa innahoo lafisq; wa innash Shayaateena la yoohoona ilaaa awliyaaa’ihim liyujaadilookum wa in ata’tumoohum innakum lamushrikoon
*6:121 Dietary prohibitions instituted by other than God represent idolatry.
