﴿ يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا لَقِيتُمُ ٱلَّذِينَ كَفَرُوا۟ زَحْفًۭا فَلَا تُوَلُّوهُمُ ٱلْأَدْبَارَ ﴾

“O YOU who have attained to faith! When you meet in battle those who are bent on denying the truth, advancing in great force, do not turn your backs on them:”

(O ye who believe, When ye meet those who disbelieve) at Badr (in battle, turn not your backs to them) in defeat.
