﴿ أَفَأَمِنُوٓا۟ أَن تَأْتِيَهُمْ غَٰشِيَةٌۭ مِّنْ عَذَابِ ٱللَّهِ أَوْ تَأْتِيَهُمُ ٱلسَّاعَةُ بَغْتَةًۭ وَهُمْ لَا يَشْعُرُونَ ﴾

“Do they, then, feel free from the fear that there might fall upon them the overwhelming terror of God's chastisement, or that the Last Hour might come upon them of a sudden, without their being aware [of its approach]?”

Do they deem themselves secure from the coming upon them of a pall a calamity enveloping them of God’s chastisement or the coming of the Hour upon them suddenly while they are unaware? of the time of its arrival beforehand?
