قُلْ هَلُمَّ شُهَدَاءَكُمُ الَّذِينَ يَشْهَدُونَ أَنَّ اللَّهَ حَرَّمَ هَٰذَا ۖ فَإِنْ شَهِدُوا فَلَا تَشْهَدْ مَعَهُمْ ۚ وَلَا تَتَّبِعْ أَهْوَاءَ الَّذِينَ كَذَّبُوا بِآيَاتِنَا وَالَّذِينَ لَا يُؤْمِنُونَ بِالْآخِرَةِ وَهُمْ بِرَبِّهِمْ يَعْدِلُونَ
Say: "Bring forward your witnesses who could bear witness that God has forbidden [all] this!" -and if they bear witness [falsely], do not bear witness with them; and do not follow the errant views of those who have given the lie to Our messages, nor of those who believe not in the life to come, and who regard other powers as their Sustainer's equals!
