Read Ruku 147 of the Quran

إِذْ يُغَشِّيكُمُ ٱلنُّعَاسَ أَمَنَةًۭ مِّنْهُ وَيُنَزِّلُ عَلَيْكُم مِّنَ ٱلسَّمَآءِ مَآءًۭ لِّيُطَهِّرَكُم بِهِۦ وَيُذْهِبَ عَنكُمْ رِجْزَ ٱلشَّيْطَـٰنِ وَلِيَرْبِطَ عَلَىٰ قُلُوبِكُمْ وَيُثَبِّتَ بِهِ ٱلْأَقْدَامَ ﴿١١﴾

[Remember] when He overwhelmed you with drowsiness [giving] security from Him and sent down upon you from the sky, rain by which to purify you and remove from you the evil [suggestions] of Satan and to make steadfast your hearts and plant firmly thereby your feet.

إِذْ يُوحِى رَبُّكَ إِلَى ٱلْمَلَـٰٓئِكَةِ أَنِّى مَعَكُمْ فَثَبِّتُوا۟ ٱلَّذِينَ ءَامَنُوا۟ ۚ سَأُلْقِى فِى قُلُوبِ ٱلَّذِينَ كَفَرُوا۟ ٱلرُّعْبَ فَٱضْرِبُوا۟ فَوْقَ ٱلْأَعْنَاقِ وَٱضْرِبُوا۟ مِنْهُمْ كُلَّ بَنَانٍۢ ﴿١٢﴾

[Remember] when your Lord inspired to the angels, "I am with you, so strengthen those who have believed. I will cast terror into the hearts of those who disbelieved, so strike [them] upon the necks and strike from them every fingertip."

ذَٰلِكَ بِأَنَّهُمْ شَآقُّوا۟ ٱللَّهَ وَرَسُولَهُۥ ۚ وَمَن يُشَاقِقِ ٱللَّهَ وَرَسُولَهُۥ فَإِنَّ ٱللَّهَ شَدِيدُ ٱلْعِقَابِ ﴿١٣﴾

That is because they opposed Allah and His Messenger. And whoever opposes Allah and His Messenger - indeed, Allah is severe in penalty.

ذَٰلِكُمْ فَذُوقُوهُ وَأَنَّ لِلْكَـٰفِرِينَ عَذَابَ ٱلنَّارِ ﴿١٤﴾

"That [is yours], so taste it." And indeed for the disbelievers is the punishment of the Fire.

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا لَقِيتُمُ ٱلَّذِينَ كَفَرُوا۟ زَحْفًۭا فَلَا تُوَلُّوهُمُ ٱلْأَدْبَارَ ﴿١٥﴾

O you who have believed, when you meet those who disbelieve advancing [for 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 Allah, 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 Allah who killed them. And you threw not, [O Muhammad], when you threw, but it was Allah who threw that He might test the believers with a good test. Indeed, Allah is Hearing and Knowing.

ذَٰلِكُمْ وَأَنَّ ٱللَّهَ مُوهِنُ كَيْدِ ٱلْكَـٰفِرِينَ ﴿١٨﴾

That [is so], and [also] that Allah 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 victory - the 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 Allah is with the believers.
