Al-Kahf (الكهف)
Chapter 18 - The Cave
فَمَا ٱسْطَٰعُوٓا۟ أَن يَظْهَرُوهُ وَمَا ٱسْتَطَٰعُوا۟ لَهُۥ نَقْبًۭا
Famas taa'ooo any yazharoohu wa mastataa'oo lahoo naqbaa
So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration.
Quran 18:97 - Surah Al-Kahf
قَالَ مَا مَكَّنِّى فِيهِ رَبِّى خَيْرٌۭ فَأَعِينُونِى بِقُوَّةٍ أَجْعَلْ بَيْنَكُمْ وَبَيْنَهُمْ رَدْمًا
He said, "That in which my Lord has established me is better [than what you offer], but assist me with strength; I will make between you and them a dam.
ءَاتُونِى زُبَرَ ٱلْحَدِيدِ ۖ حَتَّىٰٓ إِذَا سَاوَىٰ بَيْنَ ٱلصَّدَفَيْنِ قَالَ ٱنفُخُوا۟ ۖ حَتَّىٰٓ إِذَا جَعَلَهُۥ نَارًۭا قَالَ ءَاتُونِىٓ أُفْرِغْ عَلَيْهِ قِطْرًۭا
Bring me sheets of iron" - until, when he had leveled [them] between the two mountain walls, he said, "Blow [with bellows]," until when he had made it [like] fire, he said, "Bring me, that I may pour over it molten copper."
فَمَا ٱسْطَٰعُوٓا۟ أَن يَظْهَرُوهُ وَمَا ٱسْتَطَٰعُوا۟ لَهُۥ نَقْبًۭا
So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration.
قَالَ هَٰذَا رَحْمَةٌۭ مِّن رَّبِّى ۖ فَإِذَا جَآءَ وَعْدُ رَبِّى جَعَلَهُۥ دَكَّآءَ ۖ وَكَانَ وَعْدُ رَبِّى حَقًّۭا
[Dhul-Qarnayn] said, "This is a mercy from my Lord; but when the promise of my Lord comes, He will make it level, and ever is the promise of my Lord true."
۞ وَتَرَكْنَا بَعْضَهُمْ يَوْمَئِذٍۢ يَمُوجُ فِى بَعْضٍۢ ۖ وَنُفِخَ فِى ٱلصُّورِ فَجَمَعْنَٰهُمْ جَمْعًۭا
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.
