Those who remained behind 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.

Those who were left behind were happy to stay behind when God’s Messenger set out; they hated the thought of striving in God’s way with their possessions and their persons. They said to one another, ‘Do not go [to war] in this heat.’ Say, ‘Hellfire is hotter.’ If only they understood!

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!
