Qur'an 9:13

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

Will ye not fight a folk who broke their solemn pledges, and purposed to drive out the messenger and did attack you first? What! Fear ye them? Now Allah hath more right that ye should fear Him, if ye are believers.
