9:81
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
9:81
Those who stayed behind rejoiced at their staying behind the Messenger of God. And they hated to strive with their wealth and their lives in God’s way. And they said, “Do not venture out in the heat.” Say, “The Fire of Hell is much hotter, if they only understood.” - Talal Itani (English)
