The word(s) "impure" appears 7 time(s) in 3 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) "Those who follow the messenger, the unlettered Prophet, whom they find mentioned in their own (scriptures),- in the law and the Gospel;- for he commands them what is just and forbids them what is evil; he allows them as lawful what is good (and pure) and prohibits them from what is bad (and impure); He releases them from their heavy burdens and from the yokes that are upon them. So it is those who believe in him, honour him, help him, and follow the light which is sent down with him,- it is they who will prosper."

(2) In order that Allah may separate the impure from the pure, put the impure, one on another, heap them together, and cast them into Hell. They will be the ones to have lost.

(3) Women impure are for men impure, and men impure for women impure and women of purity are for men of purity, and men of purity are for women of purity: these are not affected by what people say: for them there is forgiveness, and a provision honourable.
