The word(s) "confound" appears 3 time(s) in 3 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Hast thou not Turned thy vision to one who disputed with Abraham About his Lord, because Allah had granted him power? Abraham said: "My Lord is He Who Giveth life and death." He said: "I give life and death". Said Abraham: "But it is Allah that causeth the sun to rise from the east: Do thou then cause him to rise from the West." Thus was he confounded who (in arrogance) rejected faith. Nor doth Allah Give guidance to a people unjust.

(2) Nay, it may come to them all of a sudden and confound them: no power will they have then to avert it, nor will they (then) get respite.

(3) Then were they confounded with shame: (they said), "Thou knowest full well that these (idols) do not speak!"
