﴿ قُلْ أَرَءَيْتَكُمْ إِنْ أَتَىٰكُمْ عَذَابُ ٱللَّهِ بَغْتَةً أَوْ جَهْرَةً هَلْ يُهْلَكُ إِلَّا ٱلْقَوْمُ ٱلظَّٰلِمُونَ ﴾

“Say: "Can you imagine what your condition will be if God's chastisement befalls you, either suddenly or in a [gradually] perceptible manner? [But then-] will any but evildoing folk [ever] be destroyed?”

In the last verse (45), it was said that, when the mass punishment of Allah Ta` ala came, the people who did wrong were uprooted to the last man. Said immediately after was: وَالْحَمْدُ لِلَّـهِ رَ‌بِّ الْعَالَمِينَ (And praise be to Allah, the Lord of the worlds) where the hint given is: Whenever the wrongdoers and the unjust are visited by some punishment or calamity, that is a blessing for the whole world for which people should be grateful.
