Al-Fath 48:19

قُل لِّلْمُخَلَّفِينَ مِنَ الْأَعْرَابِ سَتُدْعَوْنَ إِلَىٰ قَوْمٍ أُولِي بَأْسٍ شَدِيدٍ تُقَاتِلُونَهُمْ أَوْ يُسْلِمُونَ ۖ فَإِن تُطِيعُوا يُؤْتِكُمُ اللَّهُ أَجْرًا حَسَنًا ۖ وَإِن تَتَوَلَّوْا كَمَا تَوَلَّيْتُم مِّن قَبْلُ يُعَذِّبْكُمْ عَذَابًا أَلِيمًا

Say to those who remained behind of the bedouins, "You will be called to [face] a people of great military might; you may fight them, or they will submit. So if you obey, Allah will give you a good reward; but if you turn away as you turned away before, He will punish you with a painful punishment."

لَّيْسَ عَلَى الْأَعْمَىٰ حَرَجٌ وَلَا عَلَى الْأَعْرَجِ حَرَجٌ وَلَا عَلَى الْمَرِيضِ حَرَجٌ ۗ وَمَن يُطِعِ اللَّهَ وَرَسُولَهُ يُدْخِلْهُ جَنَّاتٍ تَجْرِي مِن تَحْتِهَا الْأَنْهَارُ ۖ وَمَن يَتَوَلَّ يُعَذِّبْهُ عَذَابًا أَلِيمًا

There is not upon the blind any guilt or upon the lame any guilt or upon the ill any guilt [for remaining behind]. And whoever obeys Allah and His Messenger - He will admit him to gardens beneath which rivers flow; but whoever turns away - He will punish him with a painful punishment.

لَّقَدْ رَضِيَ اللَّهُ عَنِ الْمُؤْمِنِينَ إِذْ يُبَايِعُونَكَ تَحْتَ الشَّجَرَةِ فَعَلِمَ مَا فِي قُلُوبِهِمْ فَأَنزَلَ السَّكِينَةَ عَلَيْهِمْ وَأَثَابَهُمْ فَتْحًا قَرِيبًا

Certainly was Allah pleased with the believers when they pledged allegiance to you, [O Muhammad], under the tree, and He knew what was in their hearts, so He sent down tranquillity upon them and rewarded them with an imminent conquest

وَعَدَكُمُ اللَّهُ مَغَانِمَ كَثِيرَةً تَأْخُذُونَهَا فَعَجَّلَ لَكُمْ هَـٰذِهِ وَكَفَّ أَيْدِيَ النَّاسِ عَنكُمْ وَلِتَكُونَ آيَةً لِّلْمُؤْمِنِينَ وَيَهْدِيَكُمْ صِرَاطًا مُّسْتَقِيمًا

Allah has promised you much booty that you will take [in the future] and has hastened for you this [victory] and withheld the hands of people from you - that it may be a sign for the believers and [that] He may guide you to a straight path.

وَأُخْرَىٰ لَمْ تَقْدِرُوا عَلَيْهَا قَدْ أَحَاطَ اللَّهُ بِهَا ۚ وَكَانَ اللَّهُ عَلَىٰ كُلِّ شَيْءٍ قَدِيرًا

And [He promises] other [victories] that you were [so far] unable to [realize] which Allah has already encompassed. And ever is Allah, over all things, competent.

وَلَوْ قَاتَلَكُمُ الَّذِينَ كَفَرُوا لَوَلَّوُا الْأَدْبَارَ ثُمَّ لَا يَجِدُونَ وَلِيًّا وَلَا نَصِيرًا

And if those [Makkans] who disbelieve had fought you, they would have turned their backs [in flight]. Then they would not find a protector or a helper.
