The Combined Forces
وَلَمَّا رَءَا ٱلْمُؤْمِنُونَ ٱلْأَحْزَابَ قَالُوا۟ هَـٰذَا مَا وَعَدَنَا ٱللَّهُ وَرَسُولُهُۥ وَصَدَقَ ٱللَّهُ وَرَسُولُهُۥ ۚ وَمَا زَادَهُمْ إِلَّآ إِيمَـٰنًا وَتَسْلِيمًا
And when the believers saw the companies, they said, "This is what Allah and His Messenger had promised us, and Allah and His Messenger spoke the truth." And it increased them only in faith and acceptance.

يَحْسَبُونَ ٱلْأَحْزَابَ لَمْ يَذْهَبُوا۟ ۖ وَإِن يَأْتِ ٱلْأَحْزَابُ يَوَدُّوا۟ لَوْ أَنَّهُم بَادُونَ فِى ٱلْأَعْرَابِ يَسْـَٔلُونَ عَنْ أَنۢبَآئِكُمْ ۖ وَلَوْ كَانُوا۟ فِيكُم مَّا قَـٰتَلُوٓا۟ إِلَّا قَلِيلًا
They think the companies have not [yet] withdrawn. And if the companies should come [again], they would wish they were in the desert among the bedouins, inquiring [from afar] about your news. And if they should be among you, they would not fight except for a little.
لَّقَدْ كَانَ لَكُمْ فِى رَسُولِ ٱللَّهِ أُسْوَةٌ حَسَنَةٌ لِّمَن كَانَ يَرْجُوا۟ ٱللَّهَ وَٱلْيَوْمَ ٱلْـَٔاخِرَ وَذَكَرَ ٱللَّهَ كَثِيرًا
There has certainly been for you in the Messenger of Allah an excellent pattern for anyone whose hope is in Allah and the Last Day and [who] remembers Allah often.
مِّنَ ٱلْمُؤْمِنِينَ رِجَالٌ صَدَقُوا۟ مَا عَـٰهَدُوا۟ ٱللَّهَ عَلَيْهِ ۖ فَمِنْهُم مَّن قَضَىٰ نَحْبَهُۥ وَمِنْهُم مَّن يَنتَظِرُ ۖ وَمَا بَدَّلُوا۟ تَبْدِيلًا
Among the believers are men true to what they promised Allah. Among them is he who has fulfilled his vow [to the death], and among them is he who awaits [his chance]. And they did not alter [the terms of their commitment] by any alteration -
لِّيَجْزِىَ ٱللَّهُ ٱلصَّـٰدِقِينَ بِصِدْقِهِمْ وَيُعَذِّبَ ٱلْمُنَـٰفِقِينَ إِن شَآءَ أَوْ يَتُوبَ عَلَيْهِمْ ۚ إِنَّ ٱللَّهَ كَانَ غَفُورًا رَّحِيمًا
That Allah may reward the truthful for their truth and punish the hypocrites if He wills or accept their repentance. Indeed, Allah is ever Forgiving and Merciful.
