Surat Al-An'aam (The Cattle) - الأنعام

وَلَا تَأْكُلُوا۟ مِمَّا لَمْ يُذْكَرِ ٱسْمُ ٱللَّهِ عَلَيْهِ وَإِنَّهُۥ لَفِسْقٌ وَإِنَّ ٱلشَّيَٰطِينَ لَيُوحُونَ إِلَىٰٓ أَوْلِيَآئِهِمْ لِيُجَٰدِلُوكُمْ وَإِنْ أَطَعْتُمُوهُمْ إِنَّكُمْ لَمُشْرِكُونَ ﴿١٢١﴾

And do not eat of that on which Allah's name has not been mentioned, and that is most surely a transgression; and most surely the Shaitans suggest to their friends that they should contend with you; and if you obey them, you shall most surely be polytheists.
