یٰۤاَیُّهَا النَّاسُ اتَّقُوْا رَبَّكُمْ ۚ— اِنَّ زَلْزَلَةَ السَّاعَةِ شَیْءٌ عَظِیْمٌ ۟يٰۤـاَيُّهَا النَّاسُ اتَّقُوۡا رَبَّكُمۡۚ اِنَّ زَلۡزَلَةَ السَّاعَةِ شَىۡءٌ عَظِيۡمٌ
O People! Fear your Lord. The catastrophe of the Last Hour shall be terrible indeed:
— Tazkirul Quran (En)
یَوْمَ تَرَوْنَهَا تَذْهَلُ كُلُّ مُرْضِعَةٍ عَمَّاۤ اَرْضَعَتْ وَتَضَعُ كُلُّ ذَاتِ حَمْلٍ حَمْلَهَا وَتَرَی النَّاسَ سُكٰرٰی وَمَا هُمْ بِسُكٰرٰی وَلٰكِنَّ عَذَابَ اللّٰهِ شَدِیْدٌ ۟يَوۡمَ تَرَوۡنَهَا تَذۡهَلُ كُلُّ مُرۡضِعَةٍ عَمَّاۤ اَرۡضَعَتۡ وَتَضَعُ كُلُّ ذَاتِ حَمۡلٍ حَمۡلَهَا وَتَرَى النَّاسَ سُكٰرٰى وَمَا هُمۡ بِسُكٰرٰى وَلٰـكِنَّ عَذَابَ اللّٰهِ شَدِيۡدٌ
when that Day comes, every suckling mother shall forsake her infant and every pregnant woman shall cast her burden and everyone will appear intoxicated, although they are not: the punishment of God will be severe indeed.
— Tazkirul Quran (En)
Tafseer of 22:1–2
This is a literal description of some of the horrors of Doomsday, a day which will throw people into such a state of sheer horror that the mother will forget the baby at her breast and the pregnant woman will miscarry.
The earthquakes occurring in our present world give only a slight foretaste of the events of Doomsday. The onset of the great earthquake of Doomsday will make man forget everything he had considered important and due to which he had forgotten Doomsday—so much so that on that Day he will forget even his most cherished possessions and his near and dear ones.
