أَلا تُقاتِلونَ قَومًا نَكَثوا أَيمانَهُم وَهَمّوا بِإِخراجِ الرَّسولِ وَهُم بَدَءوكُم أَوَّلَ مَرَّةٍ ۚ أَتَخشَونَهُم ۚ فَاللَّهُ أَحَقُّ أَن تَخشَوهُ إِن كُنتُم مُؤمِنينَ

Will you not fight against those who broke their oaths, sought to expel the Messenger, and initiated hostilities against you? Do you fear them? God is the one you should fear, if you are believers.
