اِنَّ فِیْ ذٰلِكَ لَاٰیَةً لِّمَنْ خَافَ عَذَابَ الْاٰخِرَةِ ذٰلِكَ یَوْمٌ مَّجْمُوْعٌ لَّهُ النَّاسُ وَذٰلِكَ یَوْمٌ مَّشْهُوْدٌ ۟

Inna fee zaalika la aayatal liman khaafa 'azaabal Aakhirah; zaalika Yawmum majmoo'ul lahun naasu wa zaalika Yawmum mashhood

“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.”
