The word(s) "uncleanness" appears 2 time(s) in 2 verse(s) in Quran in Muhammad Pickthal translation.

(1) It is not for any soul to believe save by the permission of Allah. He hath set uncleanness upon those who have no sense.

(2) And stay in your houses. Bedizen not yourselves with the bedizenment of the Time of Ignorance. Be regular in prayer, and pay the poor-due, and obey Allah and His messenger. Allah's wish is but to remove uncleanness far from you, O Folk of the Household, and cleanse you with a thorough cleansing.
