Sura al-Tawbah 9:81

فَرِحَ ٱلْمُخَلَّفُونَ بِمَقْعَدِهِمْ خِلَٰفَ رَسُولِ ٱللَّـهِ وَكَرِهُوٓا۟ أَن يُجَٰهِدُوا۟ بِأَمْوَٰلِهِمْ وَأَنفُسِهِمْ فِى سَبِيلِ ٱللَّـهِ وَقَالُوا۟ لَا تَنفِرُوا۟ فِى ٱلْحَرِّ قُلْ نَارُ جَهَنَّمَ أَشَدُّ حَرًّا لَّوْ كَانُوا۟ يَفْقَهُونَ

fariḥa l-mukhallafūna bi-maqʿadihim khilāfa rasūli allāhi wa-karihū an yujāhidū bi-amwālihim wa-anfusihim fī sabīli allāhi wa-qālū lā tanfirū fī l-ḥarri qul nāru jahannama ashaddu ḥarran law kānū yafqahūna

Those who were left behind (in the Tabuk expedition) rejoiced in their inaction behind the back of the Messenger of Allah: they hated to strive and fight, with their goods and their persons, in the cause of Allah: they said, "Go not forth in the heat." Say, "The fire of Hell is fiercer in heat." If only they could understand!

Sura al-Fatḥ 48:11

سَيَقُولُ لَكَ ٱلْمُخَلَّفُونَ مِنَ ٱلْأَعْرَابِ شَغَلَتْنَآ أَمْوَٰلُنَا وَأَهْلُونَا فَٱسْتَغْفِرْ لَنَا يَقُولُونَ بِأَلْسِنَتِهِم مَّا لَيْسَ فِى قُلُوبِهِمْ قُلْ فَمَن يَمْلِكُ لَكُم مِّنَ ٱللَّـهِ شَيْـًٔا إِنْ أَرَادَ بِكُمْ ضَرًّا أَوْ أَرَادَ بِكُمْ نَفْعًۢا بَلْ كَانَ ٱللَّـهُ بِمَا تَعْمَلُونَ خَبِيرًۢا

sa-yaqūlu la-ka l-mukhallafūna mina l-aʿrābi shaghalatnā amwālunā wa-ahlūnā fastaghfir la-nā yaqūlūna bi-alsinatihim mā laysa fī qulūbihim qul fa-man yamliku la-kum mina allāhi shayʾan in arāda bikum ḍarran aw arāda bikum nafʿan bal kāna allāhu bi-mā taʿmalūna khabīran

The desert Arabs who lagged behind will say to thee: "We were engaged in (looking after) our flocks and herds, and our families: do thou then ask forgiveness for us." They say with their tongues what is not in their hearts. Say: "Who then has any power at all (to intervene) on your behalf with Allah, if His Will is to give you some loss or to give you some profit? But Allah is well acquainted with all that ye do.

Sura al-Fatḥ 48:15

سَيَقُولُ ٱلْمُخَلَّفُونَ إِذَا ٱنطَلَقْتُمْ إِلَىٰ مَغَانِمَ لِتَأْخُذُوهَا ذَرُونَا نَتَّبِعْكُمْ يُرِيدُونَ أَن يُبَدِّلُوا۟ كَلَٰمَ ٱللَّـهِ قُل لَّن تَتَّبِعُونَا كَذَٰلِكُمْ قَالَ ٱللَّـهُ مِن قَبْلُ فَسَيَقُولُونَ بَلْ تَحْسُدُونَنَا بَلْ كَانُوا۟ لَا يَفْقَهُونَ إِلَّا قَلِيلًا

sa-yaqūlu l-mukhallafūna idhā inṭalaqtum ilā maghānima li-taʾkhudhūhā dharūnā nattabiʿkum yurīdūna an yubaddilū kalāma allāhi qul lan tattabiʿūnā kadhālikum qalā allāhu min qablu fa-sa-yaqūlūna bal taḥsudūnanā bal kānū lā yafqahūna illā qalīlan

Those who lagged behind (will say), when ye (are free to) march and take booty (in war): "Permit us to follow you." They wish to change Allah's decree: Say: "Not thus will ye follow us: Allah has already declared (this) beforehand": then they will say, "But ye are jealous of us." Nay, but little do they understand (such things).

Sura al-Fatḥ 48:16

قُل لِّلْمُخَلَّفِينَ مِنَ ٱلْأَعْرَابِ سَتُدْعَوْنَ إِلَىٰ قَوْمٍ أُو۟لِى بَأْسٍ شَدِيدٍ تُقَٰتِلُونَهُمْ أَوْ يُسْلِمُونَ فَإِن تُطِيعُوا۟ يُؤْتِكُمُ ٱللَّـهُ أَجْرًا حَسَنًا وَإِن تَتَوَلَّوْا۟ كَمَا تَوَلَّيْتُم مِّن قَبْلُ يُعَذِّبْكُمْ عَذَابًا أَلِيمًا

qul lil-mukhallafīna mina l-aʿrābi sa-tudʿawna ilā qawmin ūlī baʾsin shadīdin tuqātilūnahum aw yuslimūna fa-in tuṭīʿū yuʾtikumu allāhu ajran ḥasanan wa-in tatawallaw ka-mā tawallaytum min qablu yuʿadhdhibkum ʿadhāban alīman

Say to the desert Arabs who lagged behind: "Ye shall be summoned (to fight) against a people given to vehement war: then shall ye fight, or they shall submit. Then if ye show obedience, Allah will grant you a goodly reward, but if ye turn back as ye did before, He will punish you with a grievous Penalty."
