38:15
وَمَا يَنظُرُ هَـٰٓؤُلَآءِ إِلَّا صَيْحَةً وَٰحِدَةً مَّا لَهَا مِن فَوَاقٍ
wamā yanẓuru hāulāi illā ṣayḥatan wāḥidatan mā lahā min fawāqin
all the disbelievers here are waiting for is a single blast that cannot be postponed.
And these only wait for a single Saihah [shout (i.e. the blowing of the Trumpet by the angel Isrâfil -)] there will be no pause or ending thereto [till everything will perish except Allâh (the only God full of Majesty, Bounty and Honour)].
