Ar-Rum - 30:12

وَيَوْمَ تَقُومُ السَّاعَةُ يُبْلِسُ الْمُجْرِمُونَ
[30:12]
And at the time when the hour shall come the guilty shall be in despair.
On the Day that the Hour will be established, the guilty will be struck dumb with despair.
And in the day when the Hour riseth the unrighteous will despair.
