8:40
وَإِن تَوَلَّوْا۟ فَٱعْلَمُوٓا۟ أَنَّ ٱللَّهَ مَوْلَىٰكُمْ ۚ نِعْمَ ٱلْمَوْلَىٰ وَنِعْمَ ٱلنَّصِيرُ
But if they turn away - then know that Allah is your protector. Excellent is the protector, and Excellent is the helper.

قُل لِّلَّذِينَ كَفَرُوٓا۟ إِن يَنتَهُوا۟ يُغْفَرْ لَهُم مَّا قَدْ سَلَفَ وَإِن يَعُودُوا۟ فَقَدْ مَضَتْ سُنَّتُ ٱلْأَوَّلِينَ
Say to those who have disbelieved [that] if they cease, what has previously occurred will be forgiven for them. But if they return [to hostility] - then the precedent of the former [rebellious] peoples has already taken place.
وَقَـٰتِلُوهُمْ حَتَّىٰ لَا تَكُونَ فِتْنَةٌ وَيَكُونَ ٱلدِّينُ كُلُّهُۥ لِلَّهِ ۚ فَإِنِ ٱنتَهَوْا۟ فَإِنَّ ٱللَّهَ بِمَا يَعْمَلُونَ بَصِيرٌ
And fight them until there is no fitnah and [until] the religion, all of it, is for Allah. And if they cease - then indeed, Allah is Seeing of what they do.
۞ وَٱعْلَمُوٓا۟ أَنَّمَا غَنِمْتُم مِّن شَىْءٍ فَأَنَّ لِلَّهِ خُمُسَهُۥ وَلِلرَّسُولِ وَلِذِى ٱلْقُرْبَىٰ وَٱلْيَتَـٰمَىٰ وَٱلْمَسَـٰكِينِ وَٱبْنِ ٱلسَّبِيلِ إِن كُنتُمْ ءَامَنتُم بِٱللَّهِ وَمَآ أَنزَلْنَا عَلَىٰ عَبْدِنَا يَوْمَ ٱلْفُرْقَانِ يَوْمَ ٱلْتَقَى ٱلْجَمْعَانِ ۗ وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ
And know that anything you obtain of war booty - then indeed, for Allah is one fifth of it and for the Messenger and for [his] near relatives and the orphans, the needy, and the [stranded] traveler, if you have believed in Allah and in that which We sent down to Our Servant on the day of criterion - the day when the two armies met. And Allah, over all things, is competent.
إِذْ أَنتُم بِٱلْعُدْوَةِ ٱلدُّنْيَا وَهُم بِٱلْعُدْوَةِ ٱلْقُصْوَىٰ وَٱلرَّكْبُ أَسْفَلَ مِنكُمْ ۚ وَلَوْ تَوَاعَدتُّمْ لَٱخْتَلَفْتُمْ فِى ٱلْمِيعَـٰدِ ۙ وَلَـٰكِن لِّيَقْضِىَ ٱللَّهُ أَمْرًا كَانَ مَفْعُولًا لِّيَهْلِكَ مَنْ هَلَكَ عَنۢ بَيِّنَةٍ وَيَحْيَىٰ مَنْ حَىَّ عَنۢ بَيِّنَةٍ ۗ وَإِنَّ ٱللَّهَ لَسَمِيعٌ عَلِيمٌ
[Remember] when you were on the near side of the valley, and they were on the farther side, and the caravan was lower [in position] than you. If you had made an appointment [to meet], you would have missed the appointment. But [it was] so that Allah might accomplish a matter already destined - that those who perished [through disbelief] would perish upon evidence and those who lived [in faith] would live upon evidence; and indeed, Allah is Hearing and Knowing.
