They will forever live the consequences of these curses. Their suffering will never be lessened, nor will they be given respite (to amend their wrongdoing).
Sayyed Abbas Sadr-Ameli
Abiding therein forever, the torment shall not be lightened for them nor shall they be given respite
Al-muntakhab fi tafsir al-Qur'an al-Karim
Such a curse of divine wrath and malignant fate shall follow them like their shadow until the day when they are dragged in chains into Hell, confined with shackles and put to unrelenting torment nor shall their punishment be put in respite
