QS. At-Taubah [9:12]
Repentance
وَاِنْنَّكَثُوْٓااَيْمَانَهُمْمِّنْبَعْدِعَهْدِهِمْوَطَعَنُوْافِيْدِيْنِكُمْفَقَاتِلُوْٓااَىِٕمَّةَالْكُفْرِاِنَّهُمْلَآاَيْمَانَلَهُمْلَعَلَّهُمْيَنْتَهُوْنَ١٢
wa‑in nakatsuu aymaanahum min ba'di 'ahdihim watha'anuu fii diinikum faqaatiluu a‑immata alkufri innahum laa aymaana lahum la'allahum yantahuuna
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. [12]
