يَوْمَ يَسْمَعُونَ الصَّيْحَةَ بِالْحَقِّ ذَلِكَ يَوْمُ الْخُرُوجِ
[50:42]
The day when they shall hear the cry in truth; that is the day of coming forth.
The Day when they will hear a (mighty) Blast in (very) truth: that will be the Day of Resurrection.
The day when they will hear the (Awful) Cry in truth. That is the day of coming forth (from the graves).
