The same gesture in both camps
Both camps often make the same gesture: they toil, strive, make contact, disavow, confess their wrongs. The text does not tell them apart by the presence of the gesture, but by its direction and its fruit. The translation therefore keeps the same word on both sides.
On the Last Day, two groups of faces: some "toiling, exhausted" (88:3), others "pleased with their effort" (88:9). All have toiled; the fruit differs. "Your efforts are indeed diverse." (92:4).
The same verb يسعى ("to strive") describes Fir'awn who "turned his back, striving" (79:22) and the blind man "who came to you striving" (80:8). The effort is the same; the direction is opposite.
The same word of disavowal is in the mouth of Ibrahim and those with him: "We are clear of you" (60:4), out of fidelity; and in that of the Diverter, after pushing the human to disown: "I am clear of you" (59:16).
The same confession saves or avails nothing depending on the moment. Dhu'n-Nun calls out in the darkness: "I have indeed been among the wrongdoers!" (21:87), and he is saved. The stricken cities say: "Woe to us — we have indeed been wrongdoers!" (21:14), but too late.
