Sura 18 Al-Kahf (The Cave), ayah 97

1. فَمَا اسْطَاعُوا أَنْ يَظْهَرُوهُ وَمَا اسْتَطَاعُوا لَهُ نَقْبًا

   Translation by words

   فَمَا

   So not

   ٱسْطَٰعُوٓا۟

   they were able

   أَن

   to

   يَظْهَرُوهُ

   scale it

   وَمَا

   and not

   ٱسْتَطَٰعُوا۟

   they were able

   لَهُۥ

   in it

   نَقْبًا

   (to do) any penetration.

   So Gog and Magog were unable to pass over it, nor were they able (to effect) in it any penetration.

   18:97
