Hicr 39-40:

•  İblis:' Ya Rabbi!, Beni doğru yoldan dışlamana karşılık, yemin ederim ki, bende onlara dünyada günahları süslü göstereceğim ve ancak senin ihlasa erdirdiğin kulların(الْمُخْلَصِينَ) hariç, onların hepsini yoldan çıkaracağım' dedi.

  خ ل ص  (ḵ-l-ṣ) -> related to making sincere, short, pure, to remove  impurities; to making clear.
  خَلَصَ “ ” (khalas): to be rid of all adulteration and impurities and to become pure.
  خَلَصَ مِنَ الْقَوْمِ “ ” (khalasa minal qaum): he separated from the nation and became a recluse {T}.
  اخَْلصََ الشَّیْءَ “ ” (akhlasah shaiyi): made something pure; selected it {M}.
  المَخُلْ ص“ ” (akhlasu): someone who has been separated from the others and selected for some purpose {T}.
  Raghib says “ الَخْاَل ص ” (al-khaalis) and “ الَصَّافیِ ” (as-safee) have the same meaning: but “ الَصَّافیِ ” (as-safee) can sometimes be used for something which is already pure.
  خَالِصٌ “ ” (khaalis) is that which has been purified of impurities {M}.
  Ibn Faris says the basic meaning is to purify and separate the unwanted parts.)
