إِنَّ فِى ذَٰلِكَ لَءَايَةً لِّمَنْ خَافَ عَذَابَ ٱلْءَاخِرَةِ ۚ ذَٰلِكَ يَوْمٌ مَّجْمُوعٌ لَّهُ ٱلنَّاسُ وَذَٰلِكَ يَوْمٌ مَّشْهُودٌ

Most surely there is a sign in this for him who fears the chastisement of the hereafter; this is a day on which the people shall be gathered together and this is a day that shall be witnessed.
