يٰٓاَيُّهَا الَّذِيْنَ اٰمَنُوْٓا اِذَا لَقِيْتُمُ الَّذِيْنَ كَفَرُوْا زَحْفًا فَلَا تُوَلُّوْهُمُ الْاَدْبَارَۚ

Yā ayyuhal-lażīna āmanū iżā laqītumul-lażīna kafarū zaḥfan falā tuwallūhumul-adbār(a).

"O you who have believed, when you meet those who disbelieve advancing [for battle], do not turn to them your backs [in flight]."
