The word(s) "disbeliever" appears 377 time(s) in 355 verse(s) in Quran in Mohsin Khan translation.

(191) And indeed We sent to Thamud their brother Salih, saying: "Worship Allah (Alone and none else). Then look! They became two parties (believers and disbelievers) quarreling with each other."

(192) And they (the disbelievers in the Oneness of Allah) say: "When (will) this promise (be fulfilled), if you are truthful?"

(193) Verily, you cannot make the dead to hear nor can you make the deaf to hear the call (i.e. benefit them and similarly the disbelievers), when they flee, turning their backs.

(194) He said: "My Lord! For that with which You have favoured me, I will never more be a helper of the Mujrimun (criminals, disbelievers, polytheists, sinners)!"

(195) Then there came to him one of the two women, walking shyly. She said: "Verily, my father calls you that he may reward you for having watered (our flocks) for us." So when he came to him and narrated the story, he said: "Fear you not. You have escaped from the people who are Zalimun (polytheists, disbelievers, and wrong-doers)."

(196) Musa (Moses) said: "My Lord knows best him who came with guidance from Him, and whose will be the happy end in the Hereafter. Verily, the Zalimun (wrong-doers, polytheists and disbelievers in the Oneness of Allah) will not be successful."

(197) But when the truth (i.e. Muhammad صلى الله عليه وسلم with his Message) has come to them from Us, they say: "Why is he not given the like of what was given to Musa (Moses)? Did they not disbelieve in that which was given to Musa (Moses) of old? They say: "Two kinds of magic [the Taurat (Torah) and the Qur'an], each helping the other!" And they say: "Verily in both we are disbelievers."

(198) And never will your Lord destroy the towns (populations) until He sends to their mother town a Messenger reciting to them Our Verses. And never would We destroy the towns unless the people thereof are Zalimun (polytheists, wrong-doers, disbelievers in the Oneness of Allah, oppressors and tyrants).

(199) He said: "This has been given to me only because of the knowledge I possess." Did he not know that Allah had destroyed before him generations, men who were stronger than him in might and greater in the amount (of riches) they had collected? But the Mujrimun (criminals, disbelievers, polytheists, sinners) will not be questioned of their sins (because Allah knows them well, so they will be punished without being called to account).

(200) And those who had desired (for a position like) his position the day before, began to say: "Know you not that it is Allah Who enlarges the provision or restricts it to whomsoever He pleases of His slaves. Had it not been that Allah was Gracious to us, He could have caused the earth to swallow us up (also)! Know you not that the disbelievers will never be successful.
