The word(s) "confounded" appears 3 time(s) in 3 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Have you not considered him (Namrud) who disputed with Ibrahim about his Lord, because Allah had given him the kingdom? When Ibrahim said: My Lord is He who gives life and causes to die, he said: I give life and cause death. Ibrahim said: So surely Allah causes the sun to rise from the east, then make it rise from the west; thus he who disbelieved was confounded; and Allah does not guide aright the unjust people.

(2) Nay, it shall come on them all of a sudden and cause them to become confounded, so they shall not have the power to avert it, nor shall they be respited.

(3) Though they were before this, before it was sent down upon them, confounded in sure despair.
