An-Nahl 16:39

Liyubayyina lahumu allatheeyakhtalifoona feehi waliyaAAlama allatheena kafarooannahum kanoo kathibeen

[It is] so He will make clear to them [the truth of] that wherein they differ and so those who have disbelieved may know that they were liars.

(He will resurrect all of them,) so that He discloses for them what they have been disputing about, and so that those who disbelieve may know that they were liars.
