O you who have believed, when you meet those who disbelieve advancing [for battle], do not turn to them your backs [in flight].
The Saheeh International Quran Translation
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا لَقِيتُمُ ٱلَّذِينَ كَفَرُوا۟ زَحْفًا فَلَا تُوَلُّوهُمُ ٱلْأَدْبَارَO you who have believed, when you meet those who disbelieve advancing [for battle], do not turn to them your backs [in flight].
