The word(s) "disbelieves" appears 15 time(s) in 15 verse(s) in Quran in Mohsin Khan translation.

(11) He it is Who has made you successors generations after generations in the earth, so whosoever disbelieves (in Islamic Monotheism) on him will be his disbelief. And the disbelief of the disbelievers adds nothing but hatred of their Lord. And the disbelief of the disbelievers adds nothing but loss.

(12) Is one who is obedient to Allah, prostrating himself or standing (in prayer) during the hours of the night, fearing the Hereafter and hoping for the Mercy of his Lord (like one who disbelieves)? Say: "Are those who know equal to those who know not?" It is only men of understanding who will remember (i.e. get a lesson from Allah's Signs and Verses).

(13) Giving glad tidings [of Paradise to the one who believes in the Oneness of Allah (i.e. Islamic Monotheism) and fears Allah much (abstains from all kinds of sins and evil deeds) and loves Allah much (performing all kinds of good deeds which He has ordained)], and warning (of punishment in the Hell-Fire to the one who disbelieves in the Oneness of Allah), but most of them turn away, so they hear not.

(14) (Their allies deceived them) like Shaitan (Satan), when he says to man: "Disbelieve in Allah." But when (man) disbelieves in Allah, Shaitan (Satan) says: "I am free of you, I fear Allah, the Lord of the 'Alamin (mankind, jinn and all that exists)!"

(15) Save the one who turns away and disbelieves.
