Read Page 185 of the Quran

وَإِن يُرِيدُوٓا۟ أَن يَخْدَعُوكَ فَإِنَّ حَسْبَكَ ٱللَّهُ ۚ هُوَ ٱلَّذِىٓ أَيَّدَكَ بِنَصْرِهِۦ وَبِٱلْمُؤْمِنِينَ ﴿62﴾

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

وَأَلَّفَ بَيْنَ قُلُوبِهِمْ ۚ لَوْ أَنفَقْتَ مَا فِى ٱلْأَرْضِ جَمِيعًۭا مَّآ أَلَّفْتَ بَيْنَ قُلُوبِهِمْ وَلَـٰكِنَّ ٱللَّهَ أَلَّفَ بَيْنَهُمْ ۚ إِنَّهُۥ عَزِيزٌ حَكِيمٌۭ ﴿63﴾

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.

يَـٰٓأَيُّهَا ٱلنَّبِىُّ حَسْبُكَ ٱللَّهُ وَمَنِ ٱتَّبَعَكَ مِنَ ٱلْمُؤْمِنِينَ ﴿64﴾

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 مِّا۟ئَةٌۭ يَغْلِبُوٓا۟ أَلْفًۭا مِّنَ ٱلَّذِينَ كَفَرُوا۟ بِأَنَّهُمْ قَوْمٌۭ لَّا يَفْقَهُونَ ﴿65﴾

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.

ٱلْـَٔـٰنَ خَفَّفَ ٱللَّهُ عَنكُمْ وَعَلِمَ أَنَّ فِيكُمْ ضَعْفًۭا ۚ فَإِن يَكُن مِّنكُم مِّا۟ئَةٌۭ صَابِرَةٌۭ يَغْلِبُوا۟ مِا۟ئَتَيْنِ ۚ وَإِن يَكُن مِّنكُمْ أَلْفٌۭ يَغْلِبُوٓا۟ أَلْفَيْنِ بِإِذْنِ ٱللَّهِ ۗ وَٱللَّهُ مَعَ ٱلصَّـٰبِرِينَ ﴿66﴾

Now, Allah has lightened [the hardship] for you, and He knows that among you is weakness. So if there are from you one hundred [who are] steadfast, they will overcome two hundred. And if there are among you a thousand, they will overcome two thousand by permission of Allah. And Allah is with the steadfast.

مَا كَانَ لِنَبِىٍّ أَن يَكُونَ لَهُۥٓ أَسْرَىٰ حَتَّىٰ يُثْخِنَ فِى ٱلْأَرْضِ ۚ تُرِيدُونَ عَرَضَ ٱلدُّنْيَا وَٱللَّهُ يُرِيدُ ٱلْـَٔاخِرَةَ ۗ وَٱللَّهُ عَزِيزٌ حَكِيمٌۭ ﴿67﴾

It is not for a prophet to have captives [of war] until he inflicts a massacre [upon Allah 's enemies] in the land. Some Muslims desire the commodities of this world, but Allah desires [for you] the Hereafter. And Allah is Exalted in Might and Wise.

لَّوْلَا كِتَـٰبٌۭ مِّنَ ٱللَّهِ سَبَقَ لَمَسَّكُمْ فِيمَآ أَخَذْتُمْ عَذَابٌ عَظِيمٌۭ ﴿68﴾

If not for a decree from Allah that preceded, you would have been touched for what you took by a great punishment.

فَكُلُوا۟ مِمَّا غَنِمْتُمْ حَلَـٰلًۭا طَيِّبًۭا ۚ وَٱتَّقُوا۟ ٱللَّهَ ۚ إِنَّ ٱللَّهَ غَفُورٌۭ رَّحِيمٌۭ ﴿69﴾

So consume what you have taken of war booty [as being] lawful and good, and fear Allah. Indeed, Allah is Forgiving and Merciful.
