إِنَّ فِي ذَلِكَ لَآيَةً لِّمَنْ خَافَ عَذَابَ الْآخِرَةِ ذَلِكَ يَوْمٌ مَّجْمُوعٌ لَّهُ النَّاسُ وَذَلِكَ يَوْمٌ مَّشْهُودٌ
There is indeed a sign in that for those who fear the punishment of the Hereafter. That is a day on which all mankind will be gathered, and it is a day witnessed [by all creatures].
