فَرِحَ الْمُخَلَّفُوْنَ بِمَقْعَدِهِمْ خِلٰفَ رَسُوْلِ اللّٰهِ وَكَرِهُوْٓا اَنْ يُّجَاهِدُوْا بِاَمْوَالِهِمْ وَاَنْفُسِهِمْ فِيْ سَبِيْلِ اللّٰهِ وَقَالُوْا لَا تَنْفِرُوْا فِي الْحَرِّؕ قُلْ نَارُ جَهَنَّمَ اَشَدُّ حَرًّاؕ لَوْ كَانُوْا يَفْقَهُوْنَ ٨١
Translation
Those who were left behind boasted for sitting back against [the command of] the Apostle of Allah, and were reluctant to wage jihad with their possessions and persons in the way of Allah, and they said, ‘Do not go forth in this heat.’ Say, The fire of hell is severer in heat, should they understand.
