The word(s) "deluded" appears 5 time(s) in 5 verse(s) in Quran in Mohsin Khan translation.

(1) The Messiah ['Îsa (Jesus)], son of Maryam (Mary), was no more than a Messenger; many were the Messengers that passed away before him. His mother [Maryam (Mary)] was a Siddiqah [i.e. she believed in the Words of Allah and His Books (see Verse 66:12)]. They both used to eat food (as any other human being, while Allah does not eat). Look how We make the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) clear to them; yet look how they are deluded away (from the truth).

(2) Verily! It is Allah Who causes the seed-grain and the fruit-stone (like date-stone) to split and sprout. He brings forth the living from the dead, and it is He Who brings forth the dead from the living. Such is Allah, then how are you deluded away from the truth?

(3) And the Jews say: 'Uzair (Ezra) is the son of Allah, and the Christians say: Messiah is the son of Allah. That is their saying with their mouths, resembling the saying of those who disbelieved aforetime. Allah's Curse be on them, how they are deluded away from the truth!

(4) Say: "Is there of your (Allah's called) partners one that originates the creation and then repeats it?" Say: "Allah originates the creation and then He repeats it. Then how are you deluded away (from the truth)?"

(5) And on the Day that the Hour will be established, the Mujrimun (criminals, disbelievers, polytheists, sinners) will swear that they stayed not but an hour - thus were they ever deluded [away from the truth (i.e. they used to tell lies and take false oaths, and turn away from the truth) in this life of the world)]
