أَلَا تُقَٰتِلُونَ قَوْمًا نَّكَثُوٓا۟ أَيْمَٰنَهُمْ وَهَمُّوا۟ بِإِخْرَاجِ ٱلرَّسُولِ وَهُم بَدَءُوكُمْ أَوَّلَ مَرَّةٍ ۚ أَتَخْشَوْنَهُمْ ۚ فَٱللَّهُ أَحَقُّ أَن تَخْشَوْهُ إِن كُنتُم مُّؤْمِنِينَ

What! will you not fight a people who broke their oaths and aimed at the expulsion of the Apostle, and they attacked you first; do you fear them? But Allah is most deserving that you should fear Him, if you are believers.
