At-Tawba 9:81

Those who remained behind rejoiced for doing so in defiance of the Messenger of Allah, and disliked to strive in the cause of Allah with their wealth and their lives[66], and said, “Do not march forth in this heat[67].” Say, “The Fire of Hell is more intense in heat.” – If only they could understand!

[66] While in reality, Allah had prevented their participation knowing of their hypocrisy and evil intent.
[67] In the Tabuk Expedition.

Those who remained behind[495] rejoiced in their staying [at home] after [the departure of] the Messenger of Allāh and disliked to strive with their wealth and their lives in the cause of Allāh and said, "Do not go forth in the heat." Say, "The fire of Hell is more intense in heat" - if they would but understand.

[495] Literally, "were left behind [as Allāh willed]" due to their false excuses having been accepted by the Prophet (ﷺ). While pleased with their assumed deception, in reality, Allāh had prevented their participation knowing of their hypocrisy and evil intent.

81. Those who stayed away (from Tabuk expedition) rejoiced in their staying behind the Messenger of Allâh; they hated to strive and fight with their properties and their lives in the Cause of Allâh, and they said: "March not forth in the heat." Say: "The Fire of Hell is more intense 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.
