8:16

وَمَن يُوَلِّهِمْ يَوْمَئِذٍۢ دُبُرَهُۥٓ إِلَّا مُتَحَرِّفًۭا لِّقِتَالٍ أَوْ مُتَحَيِّزًا إِلَىٰ فِئَةٍۢ فَقَدْ بَآءَ بِغَضَبٍۢ مِّنَ ٱللَّهِ وَمَأْوَىٰهُ جَهَنَّمُ ۖ وَبِئْسَ ٱلْمَصِيرُ ﴿16﴾

Whoso on that day turneth his back to them, unless manoeuvring for battle or intent to join a company, he truly hath incurred wrath from Allah, and his habitation will be hell, a hapless journey's end.
