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

(21) Then Allah sent down His tranquillity upon His Apostle and upon the believers, and sent down hosts which you did not see, and chastised those who disbelieved, and that is the reward of the unbelievers.

(22) And the Jews say: Uzair is the son of Allah; and the Christians say: The Messiah is the son of Allah; these are the words of their mouths; they imitate the saying of those who disbelieved before; may Allah destroy them; how they are turned away!

(23) If you will not aid him, Allah certainly aided him when those who disbelieved expelled him, he being the second of the two, when they were both in the cave, when he said to his companion: Grieve not, surely Allah is with us. So Allah sent down His tranquillity upon him and strengthened him with hosts which you did not see, and made lowest the word of those who disbelieved; and the word of Allah, that is the highest; and Allah is Mighty, Wise.

(24) They swear by Allah that they did not speak, and certainly they did speak, the word of unbelief, and disbelieved after their Islam, and they had determined upon what they have not been able to effect, and they did not find fault except because Allah and His Apostle enriched them out of His grace; therefore if they repent, it will be good for them; and if they turn back, Allah will chastise them with a painful chastisement in this world and the hereafter, and they shall not have in the land any guardian or a helper.

(25) And the defaulters from among the dwellers of the desert came that permission may be given to them and they sat (at home) who lied to Allah and His Apostle; a painful chastisement shall afflict those of them who disbelieved.

(26) To Him is your return, of all (of you); the promise of Allah (made) in truth; surely He begins the creation in the first instance, then He reproduces it, that He may with justice recompense those who believe and do good; and (as for) those who disbelieve, they shall have a drink of hot water and painful punishment because they disbelieved.

(27) (It is only) a provision in this world, then to Us shall be their return; then We shall make them taste severe punishment because they disbelieved.

(28) But the chiefs of those who disbelieved from among his people said: We do not consider you but a mortal like ourselves, and we do not see any have followed you but those who are the meanest of us at first thought and we do not see in you any excellence over us; nay, we deem you liars.

(29) And they were overtaken by curse in this world and on the resurrection day; now surely Ad disbelieved in their Lord; now surely, away with Ad, the people of Hud.

(30) And apostles before you were certainly mocked at, but I gave respite to those who disbelieved, then I destroyed them; how then was My requital (of evil)?
