وَتَرَكْنَا بَعْضَهُمْ یَوْمَىِٕذٍ یَّمُوْجُ فِیْ بَعْضٍ وَّنُفِخَ فِی الصُّوْرِ فَجَمَعْنٰهُمْ جَمْعًا ۟

Wa taraknaa ba'dahum Yawma'iziny yamooju fee ba'dinw wa nufikha fis Soori fajama'naahum jam'aa

“On that day We shall leave them to surge like waves on one another: the trumpet will be blown, and We shall collect them all together.”
