يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا لَقِيتُمُ ٱلَّذِينَ كَفَرُوا۟ زَحْفًۭا فَلَا تُوَلُّوهُمُ ٱلْأَدْبَارَ ﴿١٥﴾
O you who have believed, when you meet those who disbelieve advancing [in battle], do not turn to them your backs [in flight].
وَمَن يُوَلِّهِمْ يَوْمَئِذٍۢ دُبُرَهُۥٓ إِلَّا مُتَحَرِّفًۭا لِّقِتَالٍ أَوْ مُتَحَيِّزًا إِلَىٰ فِئَةٍۢ فَقَدْ بَآءَ بِغَضَبٍۢ مِّنَ ٱللَّهِ وَمَأْوَىٰهُ جَهَنَّمُ ۖ وَبِئْسَ ٱلْمَصِيرُ ﴿١٦﴾
And whoever turns his back to them on such a day, unless swerving [as a strategy] for war or joining [another] company, has certainly returned with anger [upon him] from Allāh, and his refuge is Hell - and wretched is the destination.
فَلَمْ تَقْتُلُوهُمْ وَلَـٰكِنَّ ٱللَّهَ قَتَلَهُمْ ۚ وَمَا رَمَيْتَ إِذْ رَمَيْتَ وَلَـٰكِنَّ ٱللَّهَ رَمَىٰ ۚ وَلِيُبْلِىَ ٱلْمُؤْمِنِينَ مِنْهُ بَلَآءً حَسَنًا ۚ إِنَّ ٱللَّهَ سَمِيعٌ عَلِيمٌۭ ﴿١٧﴾
And you did not kill them, but it was Allāh who killed them. And you threw not, [O Muḥammad], when you threw, but it was Allāh who threw that He might test the believers with a good test. Indeed, Allāh is Hearing and Knowing.
ذَٰلِكُمْ وَأَنَّ ٱللَّهَ مُوهِنُ كَيْدِ ٱلْكَـٰفِرِينَ ﴿١٨﴾
That [is so], and [also] that Allāh will weaken the plot of the disbelievers.
إِن تَسْتَفْتِحُوا۟ فَقَدْ جَآءَكُمُ ٱلْفَتْحُ ۖ وَإِن تَنتَهُوا۟ فَهُوَ خَيْرٌۭ لَّكُمْ ۖ وَإِن تَعُودُوا۟ نَعُدْ وَلَن تُغْنِىَ عَنكُمْ فِئَتُكُمْ شَيْـًۭٔا وَلَوْ كَثُرَتْ وَأَنَّ ٱللَّهَ مَعَ ٱلْمُؤْمِنِينَ ﴿١٩﴾
If you [disbelievers] seek the decision [i.e., victory] - the decision [i.e., defeat] has come to you. And if you desist [from hostilities], it is best for you; but if you return [to war], We will return, and never will you be availed by your [large] company at all, even if it should increase; and [that is] because Allāh is with the believers.
