And those in the Fire will say to the keepers of Hell, "Supplicate your Lord to lighten for us a day from the punishment."  

And those who are in the Fire will say to the keepers of Hell, ‘Call on your Lord that He relieve us of ˹at least˺ a day, in other words, the equivalent of one day, of the chastisement!’
القرآن:٤٠:٤٩ –

وَقَالَ الَّذِينَ فِي النَّارِ لِخَزَنَةِ جَهَنَّمَ ادْعُوا رَبَّكُمْ يُخَفِّفْ عَنَّا يَوْمًا مِنَ الْعَذَابِ  

{وقال الذين في النار لخزنة جهنم ادعوا ربكم يخفف عنا يوما} أي قدر يوم {من العذاب}.
