"Have they then felt secure"—meaning: the polytheists—"that there will come to them an overwhelming [calamity] of the punishment of Allah?" He says this as an interrogation, meaning: that they are not secure. "Or that the Hour will come upon them suddenly"—meaning: unexpectedly—"while they are unaware," meaning: heedless, that is: those upon whom the Hour will be established with punishment.

Surah Yusuf from verse (108) to verse (111).
