And We will leave them that day surging over each other, and [then] the Horn will be blown, and We will assemble them in [one] assembly.
The Saheeh International Quran Translation
وَتَرَكْنَا بَعْضَهُمْ يَوْمَئِذٍ يَمُوجُ فِى بَعْضٍ وَنُفِخَ فِى ٱلصُّورِ فَجَمَعْنَٰهُمْ جَمْعًاAnd We will leave them that day surging over each other, and [then] the Horn will be blown, and We will assemble them in [one] assembly.
