21:96
حَتَّىٰٓ إِذَا فُتِحَتْ يَأْجُوجُ وَ مَأْجُوجُ وَ هُم مِّن كُلِّ حَدَبٍ يَنسِلُ ونَ
Until when [the dam of] Gog and Magog has been opened and they, from every elevation, descend
36:51
وَ نُفِخَ فِى ٱل صُّورِ فَ إِذَا هُم مِّنَ ٱلْ أَجْدَاثِ إِلَىٰ رَبِّ هِمْ يَنسِلُ ونَ
And the Horn will be blown; and at once from the graves to their Lord they will hasten.
