Hud 11:103

إِنَّ فِى ذَٰلِكَ لَـَٔايَةً لِّمَنْ خَافَ عَذَابَ ٱلْـَٔاخِرَةِ ۚ ذَٰلِكَ يَوْمٌ مَّجْمُوعٌ لَّهُ ٱلنَّاسُ وَذَٰلِكَ يَوْمٌ مَّشْهُودٌ

Inna fī dhālika laāyatan liman khāfa ʿadhāba l-ākhirati dhālika yawmun majmūʿun lahu l-nāsu wadhālika yawmun mashhūdun

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.
