Qur'an 11:103 · Hud

إِنَّ فِى ذَٰلِكَ لَءَايَةًۭ لِّمَنْ خَافَ عَذَابَ ٱلْءَاخِرَةِ ۚ ذَٰلِكَ يَوْمٌۭ مَّجْمُوعٌۭ لَّهُ ٱلنَّاسُ وَذَٰلِكَ يَوْمٌۭ مَّشْهُودٌۭ

(103) Indeed in that is a sign for those who fear the punishment of the Hereafter. That is a Day for which the people will be collected, and that is a Day [which will be] witnessed.
