Surah 9. Al-Tawba
Ayah 81 - 83
81 فَرِحَ ٱلْمُخَلَّفُونَ بِمَقْعَدِهِمْ خِلَـٰفَ رَسُولِ ٱللَّهِ وَكَرِهُوٓا۟ أَن يُجَـٰهِدُوا۟ بِأَمْوَٰلِهِمْ وَأَنفُسِهِمْ فِى سَبِيلِ ٱللَّهِ وَقَالُوا۟ لَا تَنفِرُوا۟ فِى ٱلْحَرِّ ۗ قُلْ نَارُ جَهَنَّمَ أَشَدُّ حَرًّا ۚ لَّوْ كَانُوا۟ يَفْقَهُونَ
82 فَلْيَضْحَكُوا۟ قَلِيلًا وَلْيَبْكُوا۟ كَثِيرًا جَزَآءًۢ بِمَا كَانُوا۟ يَكْسِبُونَ
83 فَإِن رَّجَعَكَ ٱللَّهُ إِلَىٰ طَآئِفَةٍ مِّنْهُمْ فَٱسْتَـْٔذَنُوكَ لِلْخُرُوجِ فَقُل لَّن تَخْرُجُوا۟ مَعِىَ أَبَدًا وَلَن تُقَـٰتِلُوا۟ مَعِىَ عَدُوًّا ۖ إِنَّكُمْ رَضِيتُم بِٱلْقُعُودِ أَوَّلَ مَرَّةٍ فَٱقْعُدُوا۟ مَعَ ٱلْخَـٰلِفِينَ
[81-83] Those who were allowed to remain behind, were happy that they had not gone with Allah's Messenger, and had stayed at home, for they did not like to do Jihad in the Way of Allah with their possessions and their persons. They said to the people, "Do not go forth in this heat." Say to them, "The Fire of Hell is much hotter than this"; would that they understood this! Let them now laugh little and weep much for the recompense of what they have been earning is such (that they should weep). Henceforth, if Allah brings you among them and any of them asks your leave to go forth for Jihad. say to them plainly, "Now you shall never be allowed to go forth with me nor to fight an enemy in my company; as you were pleased to stay behind the first time, now you stay at home with those who stay behind".
