Surah At-Tawbah, Verse 13

أَلَا تُقَٰتِلُونَ قَوۡمٗا نَّكَثُوٓاْ أَيۡمَٰنَهُمۡ وَهَمُّواْ بِإِخۡرَاجِ ٱلرَّسُولِ وَهُم بَدَءُوكُمۡ أَوَّلَ مَرَّةٍۚ أَتَخۡشَوۡنَهُمۡۚ فَٱللَّهُ أَحَقُّ أَن تَخۡشَوۡهُ إِن كُنتُم مُّؤۡمِنِينَ١٣

alā tuqātilūna qawman nakathū aymānahum wahammū bi-ikh'rāji l-rasūli wahum badaūkum awwala marratin atakhshawnahum fal-lahu aḥaqqu an takhshawhu in kuntum mu'minīna

Would you not fight against a people who broke their oaths and determined to expel the Messenger, and they had begun [the attack upon] you the first time? Do you fear them? But Allāh has more right that you should fear Him, if you are [truly] believers.
