The Spoils of War
وَأَلَّفَ بَيْنَ قُلُوبِهِمْ ۚ لَوْ أَنفَقْتَ مَا فِى ٱلْأَرْضِ جَمِيعًا مَّآ أَلَّفْتَ بَيْنَ قُلُوبِهِمْ وَلَـٰكِنَّ ٱللَّهَ أَلَّفَ بَيْنَهُمْ ۚ إِنَّهُۥ عَزِيزٌ حَكِيمٌ
And brought together their hearts. If you had spent all that is in the earth, you could not have brought their hearts together; but Allah brought them together. Indeed, He is Exalted in Might and Wise.

And if they incline to peace, then incline to it [also] and rely upon Allah. Indeed, it is He who is the Hearing, the Knowing.
وَإِن يُرِيدُوٓا۟ أَن يَخْدَعُوكَ فَإِنَّ حَسْبَكَ ٱللَّهُ ۚ هُوَ ٱلَّذِىٓ أَيَّدَكَ بِنَصْرِهِۦ وَبِٱلْمُؤْمِنِينَ
But if they intend to deceive you - then sufficient for you is Allah. It is He who supported you with His help and with the believers
يَـٰٓأَيُّهَا ٱلنَّبِىُّ حَسْبُكَ ٱللَّهُ وَمَنِ ٱتَّبَعَكَ مِنَ ٱلْمُؤْمِنِينَ
O Prophet, sufficient for you is Allah and for whoever follows you of the believers.
يَـٰٓأَيُّهَا ٱلنَّبِىُّ حَرِّضِ ٱلْمُؤْمِنِينَ عَلَى ٱلْقِتَالِ ۚ إِن يَكُن مِّنكُمْ عِشْرُونَ صَـٰبِرُونَ يَغْلِبُوا۟ مِا۟ئَتَيْنِ ۚ وَإِن يَكُن مِّنكُم مِّا۟ئَةٌ يَغْلِبُوٓا۟ أَلْفًا مِّنَ ٱلَّذِينَ كَفَرُوا۟ بِأَنَّهُمْ قَوْمٌ لَّا يَفْقَهُونَ
O Prophet, urge the believers to battle. If there are among you twenty [who are] steadfast, they will overcome two hundred. And if there are among you one hundred [who are] steadfast, they will overcome a thousand of those who have disbelieved because they are a people who do not understand.
