Those who were left behind (in the Tabuk expedition) rejoiced in their inaction behind the back of the Messenger of Allah: they hated to strive and fight, with their goods and their persons, in the cause of Allah: they said, "Go not forth in the heat." Say, "The fire of Hell is fiercer in heat." If only they could understand! 81 So let them laugh a little, for weep they will, more as retribution for what they have done. 82 So, if God returns thee to a party of them and they ask leave of thee to go forth, say: 'You shall not go forth with me ever, and you shall not fight with me any enemy. You were well-pleased to tarry the first time, so now tarry with those behind.' 83 And do not pray [the funeral prayer, O Muhammad], over any of them who has died - ever - or stand at his grave. Indeed, they disbelieved in Allah and His Messenger and died while they were defiantly disobedient. 84 Nor let their wealth nor their (following in) sons dazzle thee: Allah's plan is to punish them with these things in this world, and that their souls may perish in their (very) denial of Allah. 85 And whenever any Surah is sent down commanding: believe in Allah and strive hard in the company of His apostle, the opulent among them ask leave of thee, and say: leave us; we shall be with those who stay. 86 They are well-pleased to be with those behind, and a seal has been set upon their hearts, so the they understand not. 87 But the Messenger of God and the believers with him fought for the cause of God with their possessions and in person and their reward will be all good things and everlasting happiness. 88 Allah has prepared for them gardens beneath which rivers flow, to abide in them; that is the great achievement. 89
