Surah Yusuf (Joseph), Verse 107

اَفَاَمِنُوْۤا اَنْ تَاْتِیَهُمْ غَاشِیَةٌ مِّنْ عَذَابِ اللّٰهِ اَوْ تَاْتِیَهُمُ السَّاعَةُ بَغْتَةً وَّهُمْ لَا یَشْعُرُوْنَ ۟

Afa aminooo an taatiya hum ghaashiyatum min 'azaabil laahi aw taatiyahumus Saa'atu baghtatanw wa hum laa yash'uroon

“Do they then feel secure from the coming against them of the covering veil of the wrath of Allah,- or of the coming against them of the (final) Hour all of a sudden while they perceive not?”
