As-Sajdah 32:14

Fathooqoo bima naseetum liqaayawmikum hatha inna naseenakum wathooqooAAathaba alkhuldi bima kuntum taAAmaloon

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."

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.
