Hud - 11:103

إِنَّ فِي ذَلِكَ لآيَةً لِّمَنْ خَافَ عَذَابَ الآخِرَةِ ذَلِكَ يَوْمٌ مَّجْمُوعٌ لَّهُ النَّاسُ وَذَلِكَ يَوْمٌ مَّشْهُودٌ
[11:103]
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.
In that is a Sign for those who fear the penalty of the Hereafter: that is a Day for which mankind will be gathered together: that will be a Day of Testimony.
Lo! herein verily there is a portent for those who fear the doom of the Hereafter. That is a day unto which mankind will be gathered, and that is a day that will be witnessed.
