قُلْ هَلُمَّ شُهَدَآءَكُمُ ٱلَّذِينَ يَشْهَدُونَ أَنَّ ٱللَّهَ حَرَّمَ هَٰذَا ۖ فَإِن شَهِدُوا۟ فَلَا تَشْهَدْ مَعَهُمْ ۚ وَلَا تَتَّبِعْ أَهْوَآءَ ٱلَّذِينَ كَذَّبُوا۟ بِـَٔايَٰتِنَا وَٱلَّذِينَ لَا يُؤْمِنُونَ بِٱلْءَاخِرَةِ وَهُم بِرَبِّهِمْ يَعْدِلُونَ
Say: Come, bring your witnesses who can bear witness that Allah forbade (all) this. And if they bear witness, do not thou bear witness with them. Follow thou not the whims of those who deny Our revelations, those who believe not in the Hereafter and deem (others) equal with their Lord.
Surah Al-An'aam(6:150)
