يَا أَيُّهَا الَّذِينَ آمَنُوا قَاتِلُوا الَّذِينَ يَلُونَكُمْ مِنَ الْكُفَّارِ وَلْيَجِدُوا فِيكُمْ غِلْظَةً ۚ وَاعْلَمُوا أَنَّ اللَّهَ مَعَ الْمُتَّقِينَ 123
O you who have believed, fight those adjacent to you of the disbelievers and let them find in you harshness. And know that Allah is with the righteous.
