The word(s) "plot" appears 43 time(s) in 36 verse(s) in Quran in Abdullah Yusuf Ali translation.

(21) But grieve not over them, nor distress thyself because of their plots.

(22) Those who had been despised will say to the arrogant ones: "Nay! it was a plot (of yours) by day and by night: Behold! Ye (constantly) ordered us to be ungrateful to Allah and to attribute equals to Him!" They will declare (their) repentance when they see the Penalty: We shall put yokes on the necks of the Unbelievers: It would only be a requital for their (ill) Deeds.

(23) If any do seek for glory and power,- to Allah belong all glory and power. To Him mount up (all) Words of Purity: It is He Who exalts each Deed of Righteousness. Those that lay plots of Evil,- for them is a Penalty terrible; and the plotting of such will be void (of result).

(24) On account of their arrogance in the land and their plotting of Evil, but the plotting of Evil will hem in only the authors thereof. Now are they but looking for the way the ancients were dealt with? But no change wilt thou find in Allah's way (of dealing): no turning off wilt thou find in Allah's way (of dealing).

(25) But (there were people) before them, who denied (the Signs),- the People of Noah, and the Confederates (of Evil) after them; and every People plotted against their prophet, to seize him, and disputed by means of vanities, therewith to condemn the Truth; but it was I that seized them! and how (terrible) was My Requital!

(26) Now, when he came to them in Truth, from Us, they said, "Slay the sons of those who believe with him, and keep alive their females," but the plots of Unbelievers (end) in nothing but errors (and delusions)!...

(27) "The ways and means of (reaching) the heavens, and that I may mount up to the god of Moses: But as far as I am concerned, I think (Moses) is a liar!" Thus was made alluring, in Pharaoh's eyes, the evil of his deeds, and he was hindered from the Path; and the plot of Pharaoh led to nothing but perdition (for him).

(28) Then Allah saved him from (every) ill that they plotted (against him), but the burnt of the Penalty encompassed on all sides the People of Pharaoh.

(29) Or do they intend a plot (against thee)? But those who defy Allah are themselves involved in a plot!

(30) The Day when their plotting will avail them nothing and no help shall be given them.
