Translation of the verse 81 from Surah At-Taubah : Number of verses 129 - - page 200 - Part 10.
Those who stayed away (from Tabuk expedition) rejoiced in their staying behind the Messenger of Allah; they hated to strive and fight with their properties and their lives in the Cause of Allah, 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 remained behind rejoiced in their staying [at home] after [the departure of] the Messenger of Allah and disliked to strive with their wealth and their lives in the cause of Allah and said, "Do not go forth in the heat." Say, "The fire of Hell is more intensive in heat" - if they would but understand.
(9:81) Those who were allowed to remain behind, were happy that they had not gone with Allah's Messenger, and had stayed at home, for they did not like to do Jihad in the Way of Allah with their possessions and their persons. They said to the people, "Do not go forth in this heat." Say to them, "The Fire of Hell is much hotter than this"; would that they understood this!
