48:11
سَ يَقُولُ لَ كَ ٱلْ مُخَلَّفُونَ مِنَ ٱلْ أَعْرَابِ شَغَلَتْ نَآ أَمْوَٰلُ نَا وَ أَهْلُو نَا فَ ٱسْتَغْفِرْ لَ نَا يَقُولُ ونَ بِ أَلْسِنَتِ هِم مَّا لَيْسَ فِى قُلُوبِ هِمْ قُلْ فَ مَن يَمْلِكُ لَ كُم مِّنَ ٱللَّهِ شَيْـًٔا إِنْ أَرَادَ بِ كُمْ ضَرًّا أَوْ أَرَادَ بِ كُمْ نَفْعًۢا بَلْ كَانَ ٱللَّهُ بِ مَا تَعْمَلُ ونَ خَبِيرًۢا
Those who remained behind of the bedouins will say to you, "Our properties and our families occupied us, so ask forgiveness for us." They say with their tongues what is not within their hearts. Say, "Then who could prevent Allah at all if He intended for you harm or intended for you benefit? Rather, ever is Allah, with what you do, Acquainted.
48:15
سَ يَقُولُ ٱلْ مُخَلَّفُونَ إِذَا ٱنطَلَقْ تُمْ إِلَىٰ مَغَانِمَ لِ تَأْخُذُ و هَا ذَرُ و نَا نَتَّبِعْ كُمْ يُرِيدُ ونَ أَن يُبَدِّلُ وا۟ كَلَٰمَ ٱللَّهِ قُل لَّن تَتَّبِعُ و نَا كَ ذَٰلِكُمْ قَالَ ٱللَّهُ مِن قَبْلُ فَ سَ يَقُولُ ونَ بَلْ تَحْسُدُ ونَ نَا بَلْ كَانُ وا۟ لَا يَفْقَهُ ونَ إِلَّا قَلِيلًا
Those who remained behind will say when you set out toward the war booty to take it, "Let us follow you." They wish to change the words of Allah. Say, "Never will you follow us. Thus did Allah say before." So they will say, "Rather, you envy us." But [in fact] they were not understanding except a little.
48:16
قُل لِّ لْ مُخَلَّفِينَ مِنَ ٱلْ أَعْرَابِ سَ تُدْعَ وْنَ إِلَىٰ قَوْمٍ أُو۟لِى بَأْسٍ شَدِيدٍ تُقَٰتِلُ ونَ هُمْ أَوْ يُسْلِمُ ونَ فَ إِن تُطِيعُ وا۟ يُؤْتِ كُمُ ٱللَّهُ أَجْرًا حَسَنًا وَ إِن تَتَوَلَّ وْا۟ كَ مَا تَوَلَّيْ تُم مِّن قَبْلُ يُعَذِّبْ كُمْ 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."
9:118
وَ عَلَى ٱل ثَّلَٰثَةِ ٱلَّذِينَ خُلِّفُ وا۟ حَتَّىٰٓ إِذَا ضَاقَتْ عَلَيْ هِمُ ٱلْ أَرْضُ بِ مَا رَحُبَتْ وَ ضَاقَتْ عَلَيْ هِمْ أَنفُسُ هُمْ وَ ظَنُّ وٓا۟ أَن لَّا مَلْجَأَ مِنَ ٱللَّهِ إِلَّآ إِلَيْ هِ ثُمَّ تَابَ عَلَيْ هِمْ لِ يَتُوبُ وٓا۟ إِنَّ ٱللَّهَ هُوَ ٱل تَّوَّابُ ٱل رَّحِيمُ
And [He also forgave] the three who were left behind [and regretted their error] to the point that the earth closed in on them in spite of its vastness and their souls confined them and they were certain that there is no refuge from Allah except in Him. Then He turned to them so they could repent. Indeed, Allah is the Accepting of repentance, the Merciful.
9:81
فَرِحَ ٱلْ مُخَلَّفُونَ بِ مَقْعَدِ هِمْ خِلَٰفَ رَسُولِ ٱللَّهِ وَ كَرِهُ وٓا۟ أَن يُجَٰهِدُ وا۟ بِ أَمْوَٰلِ هِمْ وَ أَنفُسِ هِمْ فِى سَبِيلِ ٱللَّهِ وَ قَالُ وا۟ لَا تَنفِرُ وا۟ فِى ٱلْ حَرِّ قُلْ نَارُ جَهَنَّمَ أَشَدُّ حَرًّا لَّوْ كَانُ وا۟ يَفْقَهُ ونَ
Those who remained behind rejoiced in their staying [at home] after [the departure of] the Messenger of Allah and disliked to strive with their wealth and their lives in the cause of Allah and said, "Do not go forth in the heat." Say, "The fire of Hell is more intensive in heat" - if they would but understand.
