Surat At-Tawbah - سورة التوبة

يُرِيدُونَ أَن يُطْفِئُوا نُورَ اللَّهِ بِأَفْوَاهِهِمْ وَيَأْبَى اللَّهُ إِلَّا أَن يُتِمَّ نُورَهُ وَلَوْ كَرِهَ الْكَافِرُونَ

Muhsin Khan: They (the disbelievers, the Jews and the Christians) want to extinguish Allah's Light (with which Muhammad SAW has been sent - Islamic Monotheism) with their mouths, but Allah will not allow except that His Light should be perfected even though the Kafirun (disbelievers) hate (it).
