وَمَا يَنظُرُ هَؤُلَاء إِلَّا صَيْحَةً وَاحِدَةً مَّا لَهَا مِن فَوَاقٍ
[38:15]
Nor do these await aught but a single cry, there being no delay in it.
These (today) only wait for a single mighty Blast, which (when it comes) will brook no delay.
These wait for but one Shout, there will be no second thereto.
