Quran 21:38 — The Prophets (Al-Anbya')

They challenge: "Where is that (retribution), if you are truthful?"

[21:37] The human being is impatient by nature. I will inevitably show you My signs; do not be in such a hurry.

[21:39] If only those who disbelieve could envision themselves when they try to ward off the fire; off their faces and their backs! No one will help them then.
