Surah Al-Kahf, ayah 99

۞ وَتَرَكۡنَا بَعۡضَهُمۡ يَوۡمَئِذٖ يَمُوجُ فِي بَعۡضٖۖ وَنُفِخَ فِي ٱلصُّورِ فَجَمَعۡنَٰهُمۡ جَمۡعٗا ٩٩

Wataraknā ba'dahum yawma'idhin yamūju fī ba'din wanufikha fis-sūri fajama'nāhum jam'ā

And We will leave them that day⁸⁰⁰ surging over each other, and [then] the Horn will be blown, and We will assemble them in [one] assembly.
