Suuratul Hajj Verse 1.
يَـٰٓأَيُّهَا ٱلنَّاسُ ٱتَّقُوا۟ رَبَّكُمْ ۚ إِنَّ زَلْزَلَةَ ٱلسَّاعَةِ شَىْءٌ عَظِيمٌ﴿١
1. O mankind! Fear your Lord and be dutiful to Him! Verily, the earthquake of the Hour (of Judgement) is a terrible thing.
Tafsir Ibn Kathir Volume 6, Page 516
Allah commands His servants to have Taqwa of Him, He informs them of the terrors of the Day of Resurrection which will come to them with its earthquakes and other horrors, as He says:
﴿إِذَا زُلْزِلَتِ الاٌّرْضُ زِلْزَالَهَا – وَأَخْرَجَتِ الأَرْضُ أَثْقَالَهَا ﴾
When the earth is shaken with its (final) earthquake. And when the earth throws out its burdens. (99:1-2)
﴿وَحُمِلَتِ الاٌّرْضُ وَالْجِبَالُ فَدُكَّتَا دَكَّةً وَحِدَةً – فَيَوْمَئِذٍ وَقَعَتِ الْوَاقِعَةُ ﴾
And the earth and the mountains shall be removed from their places, and crushed with a single crushing. Then on that Day shall the (Great) Event befall. (69:14-15)
﴿إِذَا رُجَّتِ الاٌّرْضُ رَجّاً – وَبُسَّتِ الْجِبَالُ بَسّاً ﴾
When the earth will be shaken with a terrible shake. And the mountains will be powdered to dust. (56:4-5)
It was said that this earthquake will come at the end of the life span of this world, at the outset of the Hour. Ibn Jarir recorded that `Alqamah commented on Allah’s saying,
﴿إِنَّ زَلْزَلَةَ السَّاعَةِ شَىْءٌ عَظِيمٌ﴾
Verily, the earthquake of the Hour (of Judgement) is a terrible thing.
“Before the Hour.” Others said that this refers to the terror, fear, earthquakes and chaos that will happen on the Day of Resurrection, in the arena (of Judgement), after the resurrection from the graves. This was the view favored by Ibn Jarir.
