Quran 9:81 from Surah At-Tawba on Divine Marvels.
فَرِحَ ٱلۡمُخَلَّفُونَ بِمَقۡعَدِهِمۡ خِلَٰفَ رَسُولِ ٱللَّهِ وَكَرِهُوٓاْ أَن يُجَٰهِدُواْ بِأَمۡوَٰلِهِمۡ وَأَنفُسِهِمۡ فِي سَبِيلِ ٱللَّهِ وَقَالُواْ لَا تَنفِرُواْ فِي ٱلۡحَرِّۗ قُلۡ نَارُ جَهَنَّمَ أَشَدُّ حَرّٗاۚ لَّوۡ كَانُواْ يَفۡقَهُونَ
English translation: Rejoice those who remained behind in their staying behind (the) Messenger (of) Allah and they disliked to strive with their wealth and their lives in (the) way (of) Allah and they said (Do) not go forth in the heat Say (The) Fire (of) Hell (is) more intense (in) heat If (only) they could understand
