Those who did not take part in the battle (of Tabuk), were glad about their staying home against the order of the Messenger of God. They did not want to fight for the cause of God with their property and in person and said, "Do not march (to the battle) on the hot days." (Muhammad), tell them, "The heat of hell fire is much more severe, if only you would understand." 81 So let them laugh a little, for weep they will, more as retribution for what they have done. 82 If, then, Allah bring thee back to any of them, and they ask thy permission to come out (with thee), say: "Never shall ye come out with me, nor fight an enemy with me: for ye preferred to sit inactive on the first occasion: Then sit ye (now) with those who lag 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 when a surah was revealed [enjoining them] to believe in Allah and to fight with His Messenger, those of wealth among them asked your permission [to stay back] and said, "Leave us to be with them who sit [at home]." 86 They were content to be with those who stayed behind, a seal was set upon their hearts, so they do not understand. 87 But Messenger, and the believers with him, have struggled with their possessions and their selves, and those -- for them await the good things; those -- they are the prosperers. 88 Allah has prepared for them gardens underneath which rivers flow, in which they shall live for ever. That is the greatest winning. 89
