Quran 16:46 — The Bee (Al-Nahl)

It may strike them while they are asleep; they can never escape.

[16:45] Did those who scheme evil schemes guarantee that GOD will not cause the earth to swallow them, or that the retribution will not come to them when they least expect it?

[16:47] Or it may strike them while they are fearfully expecting it. Your Lord is Compassionate, Most Merciful.
