Surah Al-Hajj — Ayah 1 (22:1)
يَٰٓأَيُّهَا ٱلنَّاسُ ٱتَّقُواْ رَبَّكُمۡۚ إِنَّ زَلۡزَلَةَ ٱلسَّاعَةِ شَيۡءٌ عَظِيمٞ ١
English translation (Saheeh International)
O mankind, fear your Lord. Indeed, the convulsion of the [final] Hour is a terrible thing.
Brief commentary
O people, be mindful of your Lord by carrying out what He has ordered you and desisting from what He has forbidden you. The earthquake and other horrors that will accompany the Day of Judgment are a grave matter, for which it is necessary to prepare through actions which please Allah.
