The word(s) "deluded" appears 14 time(s) in 13 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) If thou ask them, who created them, they will certainly say, Allah: How then are they deluded away (from the Truth)?

(12) Through which are deluded (away from the Truth) such as would be deluded.

(13) When thou lookest at them, their exteriors please thee; and when they speak, thou listenest to their words. They are as (worthless as hollow) pieces of timber propped up, (unable to stand on their own). They think that every cry is against them. They are the enemies; so beware of them. The curse of Allah be on them! How are they deluded (away from the Truth)!
