Sūrah Al-Anfaal · The Spoils of War8 : 16
وَمَن یُوَلِّهِمۡ یَوۡمَىِٕذࣲ دُبُرَهُۥۤ إِلَّا مُتَحَرِّفࣰا لِّقِتَالٍ أَوۡ مُتَحَیِّزًا إِلَىٰ فِئَةࣲ فَقَدۡ بَاۤءَ بِغَضَبࣲ مِّنَ ٱللَّهِ وَمَأۡوَىٰهُ جَهَنَّمُۖ وَبِئۡسَ ٱلۡمَصِیرُ
“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.”
