The word(s) "ownself" appears 16 time(s) in 13 verse(s) in Quran in Mohsin Khan translation.

(11) And indeed We have created man, and We know what his ownself whispers to him. And We are nearer to him than his jugular vein (by Our Knowledge).

(12) Indeed he succeeds who purifies his ownself (i.e. obeys and performs all that Allah ordered, by following the true Faith of Islamic Monotheism and by doing righteous good deeds).

(13) And indeed he fails who corrupts his ownself (i.e. disobeys what Allah has ordered by rejecting the true Faith of Islamic Monotheism or by following polytheism or by doing every kind of evil wicked deeds).
