فَذُوْقُوْا بِمَا نَسِيْتُمْ لِقَاۤءَ يَوْمِكُمْ هٰذَاۚ اِنَّا نَسِيْنٰكُمْ وَذُوْقُوْا عَذَابَ الْخُلْدِ بِمَا كُنْتُمْ تَعْمَلُوْنَ ( السجدة: ١٤ )
Fazooqoo bimaa naseetum liqaaa'a yawminkum haaza innaa naseenaakum wa zooqoo 'azaabal khuldi bimaa kuntum ta'maloon (as-Sajdah 32:14)
So taste [punishment] because you forgot the meeting of this, your Day; indeed, We have [accordingly] forgotten you. And taste the punishment of eternity for what you used to do." (As-Sajdah  : 14)
1 Mufti Taqi Usmani
So, have a taste, because you had forgotten the meeting of this day of yours. We have forgotten you; and taste the eternal punishment for what you used to do.
