The word(s) "invoke" appears 33 time(s) in 32 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) That they should invoke a son for (Allah) Most Gracious.

(12) That is because Allah - He is the Reality; and those besides Him whom they invoke,- they are but vain Falsehood: verily Allah is He, Most High, Most Great.

(13) If anyone invokes, besides Allah, Any other god, he has no authority therefor; and his reckoning will be only with his Lord! and verily the Unbelievers will fail to win through!

(14) And the fifth (oath) (should be) that they solemnly invoke the curse of Allah on themselves if they tell a lie.

(15) And the fifth (oath) should be that she solemnly invokes the wrath of Allah on herself if (her accuser) is telling the truth.

(16) Those who invoke not, with Allah, any other god, nor slay such life as Allah has made sacred except for just cause, nor commit fornication; - and any that does this (not only) meets punishment.

(17) That is because Allah is the (only) Reality, and because whatever else they invoke besides Him is Falsehood; and because Allah,- He is the Most High, Most Great.

(18) He merges Night into Day, and he merges Day into Night, and he has subjected the sun and the moon (to his Law): each one runs its course for a term appointed. Such is Allah your Lord: to Him belongs all Dominion. And those whom ye invoke besides Him have not the least power.

(19) If ye invoke them, they will not listen to your call, and if they were to listen, they cannot answer your (prayer). On the Day of Judgment they will reject your "Partnership". and none, (O man!) can tell thee (the Truth) like the One Who is acquainted with all things.

(20) If indeed thou ask them who it is that created the heavens and the earth, they would be sure to say, "Allah". Say: "See ye then? the things that ye invoke besides Allah,- can they, if Allah wills some Penalty for me, remove His Penalty?- Or if He wills some Grace for me, can they keep back his Grace?" Say: "Sufficient is Allah for me! In Him trust those who put their trust."
