اَلَا تُقَاتِلُوْنَ قَوْمًا نَّكَثُوْٓا اَيْمَانَهُمْ وَهَمُّوْا بِاِخْرَاجِ الرَّسُوْلِ وَهُمْ بَدَءُوْكُمْ اَوَّلَ مَرَّةٍۗ اَتَخْشَوْنَهُمْ ۚفَاللّٰهُ اَحَقُّ اَنْ تَخْشَوْهُ اِنْ كُنْتُمْ مُّؤْمِنِيْنَ ( التوبة: ١٣ )
Alaa tuqaatiloona qawman nakasooo aimaanahum wa hammoo bi ikhraajir Rasooli wa hum bada'ookum awwala marrah; atakhshawnahum; fallaahu ahaqqu an takhshawhu in kuntum mu'mineen (at-Tawbah 9:13)
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 Allah has more right that you should fear Him, if you are [truly] believers. (At-Tawbah  : 13)

Would you not fight a people who broke their oaths and conspired to expel the Messenger, and it was they who started (fighting) against you for the first time? Do you fear them? But Allah has greater right that you fear Him, if you are believers.
