21:96
حَتَّى إِذَا فُتِحَتْ يَأْجُوجُ وَمَأْجُوجُ وَهُم مِّن كُلِّ حَدَبٍ يَنسِلُونَ
Until the Gog and Magog (people) are let through (their barrier), and they swiftly swarm from every hill.
21:97
وَاقْتَرَبَ الْوَعْدُ الْحَقُّ فَإِذَا هِيَ شَاخِصَةٌ أَبْصَارُ الَّذِينَ كَفَرُوا يَا وَيْلَنَا قَدْ كُنَّا فِي غَفْلَةٍ مِّنْ هَذَا بَلْ كُنَّا ظَالِمِينَ
Then will the true promise draw nigh (of fulfilment): then behold! the eyes of the Unbelievers will fixedly stare in horror: "Ah! Woe to us! we were indeed heedless of this; nay, we truly did wrong!"
