The word(s) "purer" appears 6 time(s) in 6 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) And when you have divorced women and they have ended-- their term (of waiting), then do not prevent them from marrying their husbands when they agree among themselves in a lawful manner; with this is admonished he among you who believes in Allah and the last day, this is more profitable and purer for you; and Allah knows while you do not know.

(2) And his people came to him, (as if) rushed on towards him, and already they did evil deeds. He said: O my people! these are my daughters-- they are purer for you, so guard against (the punishment of) Allah and do not disgrace me with regard to my guests; is there not among you one right-minded man?

(3) But if you do not find any one therein, then do not enter them until permission is given to you; and if it is said to you: Go back, then go back; this is purer for you; and Allah is Cognizant of what you do.

(4) Say to the believing men that they cast down their looks and guard their private parts; that is purer for them; surely Allah is Aware of what they do.

(5) O you who believe! do not enter the houses of the Prophet unless permission is given to you for a meal, not waiting for its cooking being finished-- but when you are invited, enter, and when you have taken the food, then disperse-- not seeking to listen to talk; surely this gives the Prophet trouble, but he forbears from you, and Allah does not forbear from the truth And when you ask of them any goods, ask of them from behind a curtain; this is purer for your hearts and (for) their hearts; and it does not behove you that you should give trouble to the Apostle of Allah, nor that you should marry his wives after him ever; surely this is grievous in the sight of Allah.

(6) O you who believe! when you consult the Apostle, then offer something in charity before your consultation; that is better for you and purer; but if you do not find, then surely Allah is Forgiving, Merciful.
