Yusuf - ১২:১০৭

أَفَأَمِنُواْ أَن تَأْتِيَهُمْ غَاشِيَةٌ مِّنْ عَذَابِ اللّهِ أَوْ تَأْتِيَهُمُ السَّاعَةُ بَغْتَةً وَهُمْ لاَ يَشْعُرُونَ
[12:107]
Do they then feel secure that there may come to them an extensive chastisement from Allah or (that) the hour may come to them suddenly while they do not perceive?
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?
Deem they themselves secure from the coming on them of a pall of Allah's punishment, or the coming of the Hour suddenly while they are unaware?
