The word(s) "purity" appears 4 time(s) in 4 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Have you not considered those who attribute purity to themselves? Nay, Allah purifies whom He pleases; and they shall not be wronged the husk of a date stone.

(2) So we desired that their Lord might give them in his place one better than him in purity and nearer to having compassion.

(3) And tenderness from Us and purity, and he was one who guarded (against evil),

(4) Those who keep aloof from the great sins and the indecencies but the passing idea; surely your Lord is liberal in forgiving. He knows you best when He brings you forth from the earth and when you are embryos in the wombs of your mothers; therefore do not attribute purity to your souls; He knows him best who guards (against evil).
