Ibrahim 14:46

They hatched their plot[34], but their plot was known to Allah; even if their plot were such that would move mountains[35].

[34] i.e., to kill the Prophet (ﷺ).
[35] But due to its feebleness, their plotting was never to remove mountains.

And they had planned their plan, but with Allāh is [recorded] their plan, even if their plan had been [sufficient] to do away with the mountains.[665]

[665] An alternative meaning is "...and their plan was not [sufficient] to do away with the mountains," i.e., it had no effect against Allāh's will.

46. Indeed, they planned their plot, and their plot was with Allâh, though their plot was not such as to remove the mountains (real mountains or the Islâmic law) from their places (as it is of no importance)[Tafsir Ibn Kathir][6].

[6] (V.14:46) It is said by some interpreters regarding this Verse that the Quraish pagans plotted against Prophet Muhammad صلى الله عليه وسلم to kill him but they failed and were unable to carry out their plot which they plotted.

Verily they have plotted their plot, and their plot is with Allah, though their plot were one whereby the mountains should be moved.
