The Sword

9:12
وَإِن نَّكَثُوٓا۟ أَيْمَـٰنَهُم مِّنۢ بَعْدِ عَهْدِهِمْ وَطَعَنُوا۟ فِى دِينِكُمْ فَقَـٰتِلُوٓا۟ أَئِمَّةَ ٱلْكُفْرِ ۙ إِنَّهُمْ لَآ أَيْمَـٰنَ لَهُمْ لَعَلَّهُمْ 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.
— Dr. Mustafa Khattab, the Clear Quran
