Translation of the verse 99 from Surah Al-Kahf : Number of verses 110 - - page 304 - Part 16.
And on that Day [i.e. the Day Ya'juj and Ma'juj (Gog and Magog) will come out], We shall leave them to surge like waves on one another, and the Trumpet will be blown, and We shall collect them all together.
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.
(18:99) And on that Day, *73 We will let loose the people to come close together tumultuously (like the waves of an ocean), and the trumpet shall be blown, and We will gather together all mankind.
*73) "On that Day": "The Day of Resurrection". As if to continue the theme of life-after-death to which Zul-Qarnain referred as the "time of my Lord's promise", the Qur'an has added verses 99-101 to it.
