The word(s) "disbelieved" appears 58 time(s) in 56 verse(s) in Quran in Muhammad Habib Shakir translation.

(31) And those who disbelieved said to their apostles: We will most certainly drive you forth from our land, or else you shall come back into our religion. So their Lord revealed to them: Most certainly We will destroy the unjust.

(32) And the Shaitan shall say after the affair is decided: Surely Allah promised you the promise of truth, and I gave you promises, then failed to keep them to you, and I had no authority over you, except that I called you and you obeyed me, therefore do not blame me but blame yourselves: I cannot be your aider (now) nor can you be my aiders; surely I disbelieved in your associating me with Allah before; surely it is the unjust that shall have the painful punishment.

(33) This is their retribution because they disbelieved in Our communications and said What! when we shall have become bones and decayed particles, shall we then indeed be raised up into a new creation?

(34) Thus it is that their recompense is hell, because they disbelieved and held My communications and My apostles in mockery.

(35) And the true promise shall draw nigh, then lo! the eyes of those who disbelieved shall be fixedly open: O woe to us! surely we were in a state of heedlessness as to this; nay, we were unjust.

(36) And the chiefs of those who disbelieved from among his people said: He is nothing but a mortal like yourselves who desires that he may have superiority over you, and if Allah had pleased, He could certainly have sent down angels. We have not heard of this among our fathers of yore:

(37) And the chiefs of his people who disbelieved and called the meeting of the hereafter a lie, and whom We had given plenty to enjoy in this world's life, said: This is nothing but a mortal like yourselves, eating of what you eat from and drinking of what you drink.

(38) And as to those who disbelieved and rejected Our communications and the meeting of the hereafter, these shall be brought over to the chastisement.

(39) This We requited them with because they disbelieved; and We do not punish any but the ungrateful.

(40) And those who were deemed weak shall say to those who were proud. Nay, (it was) planning by night and day when you told us to disbelieve in Allah and to set up likes with Him. And they shall conceal regret when they shall see the punishment; and We will put shackles on the necks of those who disbelieved; they shall not be requited but what they did.
