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

“for, whoever on that day turns his back on them-unless it be in a battle manoeuvre or in an endeavour to join another troop [of the believers] - shall indeed have earned the burden of God's condemnation, and his goal shall be hell: and how vile a journey's end!”

Whoever turns his back to them on that day the day of the encounter with them unless manœuvring turning around for battle — by pretending to be in flight as a trick while actually intending to relaunch an attack — or joining another detachment a company of Muslims calling on it for assistance he has truly incurred the wrath of God and his abode will be Hell — an evil journey’s end! an evil return it is. This threat applies so long as the numbers of disbelievers do not surpass twice that of the believers.
