Surat Al Anfal: (15-16)

{يَا أَيُّهَا الَّذِينَ آمَنُواْ إِذَا لَقِيتُمُ الَّذِينَ كَفَرُواْ زَحْفاً فَلاَ تُوَلُّوهُمُ الأَدْبَارَ} [الأنفال: 15]

15- O believers, when you approach your enemy, do not turn your backs to them and do not escape and leave you fighting brothers.

{وَمَن يُوَلِّهِمْ يَوْمَئِذٍ دُبُرَهُ إِلاَّ مُتَحَرِّفاً لِّقِتَالٍ أَوْ مُتَحَيِّزاً إِلَى فِئَةٍ فَقَدْ بَاء بِغَضَبٍ مِّنَ اللّهِ وَمَأْوَاهُ جَهَنَّمُ وَبِئْسَ الْمَصِيرُ} [الأنفال: 16]

16- Whoever escapes during the battle except the one who wants to deceive his enemy with the intention of attacking them or to take a better position or joining a group of believing fighters to attack the enemy again even if that group was another detachment, he shall enter in this concession as Ibn Kathir said. However, anyone -other than those types of people- will escape the battle is committing a major sin by which he shall incur the wrath of Allah and his place shall be Hell, and what a worse place it is!
