O you who have believed, when you encounter a company [from the enemy forces], stand firm and remember Allah much that you may be successful.

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا لَقِيتُمْ فِئَةً فَٱثْبُتُوا۟ وَٱذْكُرُوا۟ ٱللَّهَ كَثِيرًا لَّعَلَّكُمْ تُفْلِحُونَO you who have believed, when you encounter a company [from the enemy forces], stand firm and remember Allah much that you may be successful.
