﴿ فَمَا ٱسْطَٰعُوٓا۟ أَن يَظْهَرُوهُ وَمَا ٱسْتَطَٰعُوا۟ لَهُۥ نَقْبًۭا ﴾

“And thus [the rampart was built, and] their enemies were unable to scale it, and neither were they able to pierce it.”

And so they were not able to scale it, and climb over it because of the stature of its affair and its being comprehensive of forms of knowledge and arguments which they could neither repel nor take possession of; nor could they pierce it, on account of its becoming sturdy through habitus, works and invocations.
