The commentary of this surah is a brief depiction of the Day of Reckoning and its terrifying nature. Sturdy mountains will be uprooted and reduced to cotton wool. People will be confused and bewildered just like scattered moths around a light.
Among all this havoc, the Quran describes the destiny of a person being measured by the scales of Justice. Those whose good deeds are found to be heavier than their evil deeds, will be blessed with bliss and happiness, and the people whose good deeds are found to be lighter than their evil deeds, will face utter destruction and an abode of abyss.
This commentary details the significance of the fear of Allah and the great need to live a meaningful and worthy life before Allah. The manner of achieving this has also been discussed in great detail.
