Based on what you asked, I didn’t find the precise verse as what you mentioned. Even apparently there is not such a verse as much as I make research. (Although there would be an answer for it was really was available). In the meantime, as @Medi said:
It would be nice to add the Verse(s) of the Quran which you are
talking about
Since as you named. “anti-islamic page” brought it up, and perhaps they intend to make a hesitation or doubt regarding that in the mind of Muslims and non-Muslims as a Shobha. Anyhow, based on what I researched, the most related verse with what you pointed out (and probably the purposed verse) is the following verse (السوره النباء 7 & 6):
أَلَمْ نَجْعَلِ الْأَرْضَ مِهَادًا ﴿٦﴾ وَالْجِبَالَ أَوْتَادًا ﴿٧
Have We not made the earth a resting place? (6) And the mountains as
stakes? (7)
- Consequently, as you see at the verse 7, it is said that “And the
mountains as stakes? (7)” So, to the best of my knowledge (and based
on what I saw in my research, it is mentioned the mountains as the
stakes for the earth. In other word, it means mountains are
considered as stakes which are between the earth and Sky. Therefore
it is inferred from the verse that it is related to the E’jaaz
(miracle) of the Quran that connect or keep the earth by the
mountains as stakes which are invisibly connected to the sky.
- Or as another reason, as another aspect, it can be declared that the
holy Quran doesn’t mean that their shapes are exactly like pegs,
haply it would declare that they have a similar role with the pegs
(as stakes). In the meantime, some of current scientist believe that
the balancing role of the mountains is necessary in the keeping the
vita on the earth. Actually they can have the role of the pegs which
keep from shaking …
- And it can have many other reasons. We ought not to forget that there
are many mysteries in the holy Quran that human are not aware
concerning them…
Eventually, I strongly recommend you to read the following link which has illustrated more detailed regarding the mentioned matter. (Which is into Persian, Indonesian and Turkish.
