The Quran

وَقَد مَكَروا مَكرَهُم وَعِندَ اللَّهِ مَكرُهُم وَإِن كانَ مَكرُهُم لِتَزولَ مِنهُ الجِبالُ

Muhammad Asad

And [this retribution will befall all evildoers because] they devise that false imagery of theirs¹ - and all their false imagery is within God's knowledge. [And never can the blasphemers prevail against the truth - not] even if their false imagery were so [well-devised and so powerful] that mountains could be moved thereby.

Lit., "they devised their devising", i.e., their blasphemous belief in the existence of other "divine powers" side by side with God: this is the interpretation given by Tabari towards the end of his long commentary on this verse. For my rendering of the term makr, in this context, as "false imagery", see surah 13, note 62.
