Quran 6:150 from Surah Al-An'aam on Divine Marvels.
قُلۡ هَلُمَّ شُهَدَآءَكُمُ ٱلَّذِينَ يَشۡهَدُونَ أَنَّ ٱللَّهَ حَرَّمَ هَٰذَاۖ فَإِن شَهِدُواْ فَلَا تَشۡهَدۡ مَعَهُمۡۚ وَلَا تَتَّبِعۡ أَهۡوَآءَ ٱلَّذِينَ كَذَّبُواْ بِـَٔايَٰتِنَا وَٱلَّذِينَ لَا يُؤۡمِنُونَ بِٱلۡأٓخِرَةِ وَهُم بِرَبِّهِمۡ يَعۡدِلُونَ
English translation: Say Bring forward your witnesses those who testify that Allah prohibited this Then if they testify then (do) not testify with them And (do) not follow (the) desires (of) those who denied Our Signs and those who (do) not believe in the Hereafter while they with their Lord set up equals
