The word(s) "disbeliever" appears 13 time(s) in 12 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) And they followed what the Shaitans chanted of sorcery in the reign of Sulaiman, and Sulaiman was not an unbeliever, but the Shaitans disbelieved, they taught men sorcery and that was sent down to the two angels at Babel, Harut and Marut, yet these two taught no man until they had said, "Surely we are only a trial, therefore do not be a disbeliever." Even then men learned from these two, magic by which they might cause a separation between a man and his wife; and they cannot hurt with it any one except with Allah's permission, and they learned what harmed them and did not profit them, and certainly they know that he who bought it should have no share of good in the hereafter and evil was the price for which they sold their souls; had they but known this.

(2) Surely those who disbelieve and die while they are disbelievers, these it is on whom is the curse of Allah and the angels and men all;

(3) A people before you indeed asked such questions, and then became disbelievers on account of them.

(4) These are they to whom We gave the book and the wisdom and the prophecy; therefore if these disbelieve in it We have already entrusted with it a people who are not disbelievers in it.

(5) Who hinder (people) from Allah's way and seek to make it crooked, and they are disbelievers in the hereafter.

(6) Who turn away from the path of Allah and desire to make it crooked; and they are disbelievers in the hereafter.

(7) And they say: What! when we have become lost in the earth, shall we then certainly be in a new creation? Nay! they are disbelievers in the meeting of their Lord.

(8) And We never sent a warner to a town but those who led lives in ease in it said: We are surely disbelievers in what you are sent with.

(9) He it is Who made you rulers in the land; therefore whoever disbelieves, his unbelief is against himself; and their unbelief does not increase the disbelievers with their Lord in anything except hatred; and their unbelief does not increase the disbelievers in anything except loss.

(10) And they wonder that there has come to them a warner from among themselves, and the disbelievers say: This is an enchanter, a liar.
