Hud 11:99

WaotbiAAoo fee hathihi laAAnatanwayawma alqiyamati bi/sa arrifdu almarfood

And they were followed in this [world] with a curse and on the Day of Resurrection. And wretched is the gift which is given.

The curse was made to pursue them here and on the Day of Judgement. It is the evil reward to be offered.
