The word(s) "flagrant" appears 4 time(s) in 4 verse(s) in Quran in Muhammad Pickthal translation.

(1) Allah verily hath shown grace to the believers by sending unto them a messenger of their own who reciteth unto them His revelations, and causeth them to grow, and teacheth them the Scripture and wisdom; although before (he came to them) they were in flagrant error.

(2) O ye who believe! It is not lawful for you forcibly to inherit the women (of your deceased kinsmen), nor (that) ye should put constraint upon them that ye may take away a part of that which ye have given them, unless they be guilty of flagrant lewdness. But consort with them in kindness, for if ye hate them it may happen that ye hate a thing wherein Allah hath placed much good.

(3) See, how they invent lies about Allah! That of itself is flagrant sin.

(4) And whoso committeth a delinquency or crime, then throweth (the blame) thereof upon the innocent, hath burdened himself with falsehood and a flagrant crime.
