As-Sajdah 32:12

Walaw tara ithi almujrimoona nakisooruoosihim AAinda rabbihim rabbana absarnawasamiAAna faarjiAAna naAAmal salihaninna mooqinoon

If you could but see when the criminals are hanging their heads before their Lord, [saying], "Our Lord, we have seen and heard, so return us [to the world]; we will work righteousness. Indeed, we are [now] certain."

And (you will wonder) if you see the sinners hanging their heads before their Lord (and saying,) “Our Lord, we have now seen and heard, so send us back, and we will do righteous deeds. Surely, (now) we are believers.”
