Surah At-Tawbah · The Repentance · Verse 12/129

Qur'an 9:12

وَإِن نَّكَثُوٓا۟ أَيْمَٰنَهُم مِّنۢ بَعْدِ عَهْدِهِمْ وَطَعَنُوا۟ فِى دِينِكُمْ فَقَٰتِلُوٓا۟ أَئِمَّةَ ٱلْكُفْرِ ۙ إِنَّهُمْ لَآ أَيْمَٰنَ لَهُمْ لَعَلَّهُمْ يَنتَهُونَ

And if they break their oaths after their treaty and defame your religion, then fight the leaders of disbelief, for indeed, there are no oaths [sacred] to them; [fight them that] they might cease.
