Ya-Sin - 36:49

مَا يَنظُرُونَ إِلَّا صَيْحَةً وَاحِدَةً تَأْخُذُهُمْ وَهُمْ يَخِصِّمُونَ
[36:49]
They wait not for aught but a single cry which will overtake them while they yet contend with one another.
They will not (have to) wait for aught but a single Blast: it will seize them while they are yet disputing among themselves!
They await but one Shout, which will surprise them while they are disputing.
