Dr. Mustafa Khattab, the Clear Quran - Surah At-Tawbah, ayah 12

Translation of Surah At-Tawbah, ayah 12 (9:12)

وَإِن نَّكَثُوٓاْ أَيۡمَٰنَهُم مِّنۢ بَعۡدِ عَهۡدِهِمۡ وَطَعَنُواْ فِي دِينِكُمۡ فَقَٰتِلُوٓاْ أَئِمَّةَ ٱلۡكُفۡرِ إِنَّهُمۡ لَآ أَيۡمَٰنَ لَهُمۡ لَعَلَّهُمۡ يَنتَهُونَ ١٢
But if they break their oaths after making a pledge and attack your faith, then fight the champions of disbelief—who never honour their oaths—so perhaps they will desist.
