The word(s) "pure" appears 30 time(s) in 30 verse(s) in Quran in Muhammad Pickthal translation.

(11) And in like manner We awakened them that they might question one another. A speaker from among them said: How long have ye tarried? They said: We have tarried a day or some part of a day, (Others) said: Your Lord best knoweth what ye have tarried. Now send one of you with this your silver coin unto the city, and let him see what food is purest there and bring you a supply thereof. Let him be courteous and let no man know of you.

(12) O ye who believe! Follow not the footsteps of the devil. Unto whomsoever followeth the footsteps of the devil, lo! he commandeth filthiness and wrong. Had it not been for the grace of Allah and His mercy unto you, not one of you would ever have grown pure. But Allah causeth whom He will to grow. And Allah is Hearer, Knower.

(13) And if ye find no-one therein, still enter not until permission hath been given. And if it be said unto you: Go away again, then go away, for it is purer for you. Allah knoweth what ye do.

(14) Tell the believing men to lower their gaze and be modest. That is purer for them. Lo! Allah is aware of what they do.

(15) And when they mount upon the ships they pray to Allah, making their faith pure for Him only, but when He bringeth them safe to land, behold! they ascribe partners (unto Him),

(16) And if a wave enshroudeth them like awnings, they cry unto Allah, making their faith pure for Him only. But when He bringeth them safe to land, some of them compromise. None denieth Our signs save every traitor ingrate.

(17) O Ye who believe! Enter not the dwellings of the Prophet for a meal without waiting for the proper time, unless permission be granted you. But if ye are invited, enter, and, when your meal is ended, then disperse. Linger not for conversation. Lo! that would cause annoyance to the Prophet, and he would be shy of (asking) you (to go); but Allah is not shy of the truth. And when ye ask of them (the wives of the Prophet) anything, ask it of them from behind a curtain. That is purer for your hearts and for their hearts. And it is not for you to cause annoyance to the messenger of Allah, nor that ye should ever marry his wives after him. Lo! that in Allah's sight would be an enormity.

(18) (pure) as they were hidden eggs (of the ostrich).

(19) Lo! We purified them with a pure thought, remembrance of the Home (of the Hereafter).

(20) Lo! We have revealed the Scripture unto thee (Muhammad) with truth; so worship Allah, making religion pure for Him (only).
