فَرِحَ الْمُخَلَّفُونَ بِمَقْعَدِهِمْ خِلاَفَ رَسُولِ اللّهِ وَكَرِهُواْ أَن يُجَاهِدُواْ بِأَمْوَالِهِمْ وَأَنفُسِهِمْ فِي سَبِيلِ اللّهِ وَقَالُواْ لاَ تَنفِرُواْ فِي الْحَرِّ قُلْ نَارُ جَهَنَّمَ أَشَدُّ حَرًّا لَّوْ كَانُوا يَفْقَهُونَ
[9:81]
Those who were left behind were glad on account of their sitting behind Allah's Messenger and they were averse from striving m Allah's way with their property and their persons, and said: Do not go forth in the heat. Say: The fire of hell is much severe in heat. Would that they understood (it).
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!
Those who were left behind rejoiced at sitting still behind the messenger of Allah, and were averse to striving with their wealth and their lives in Allah's way. And they said: Go not forth in the heat! Say: The fire of hell is more intense of heat, if they but understood.
