M. H. Shakir, The Holy Quran; Arabic Text and English Translation; Foot-notes by M. H. Shakir (1974)
80. Ask forgiveness for them or do not ask forgiveness for them; even if you ask forgiveness for them seventy times, Allah will not forgive them; this is because they disbelieve in Allah and His Apostle, and Allah does not guide the transgressing people.
81. Those who were left behind were glad on account of their sitting behind Allah’s Apostle and they were averse from striving in Allah’s way with their property and their persons, and said: Do not go forth in the heat.* Say: The fire of hell is much severer in heat. Would that they understood (it).
82. Therefore they shall laugh little and weep much as a recompense for what they earned.
83. Therefore if Allah brings you back to a party of them, then they ask your permission to go forth, say: By no means shall you ever go forth with me and by no means shall you fight an enemy with me; surely you chose to sit the first time, therefore sit (now) with those who remain behind.
84. And never offer prayer for any one of them who dies
