The word(s) "korah" appears 4 time(s) in 4 verse(s) in Quran in Muhammad Pickthal translation.

(1) Now korah was of Moses' folk, but he oppressed them; and We gave him so much treasure that the stores thereof would verily have been a burden for a troop of mighty men. When his own folk said unto him: Exult not; lo! Allah loveth not the exultant;

(2) Then went he forth before his people in his pomp. Those who were desirous of the life of the world said: Ah, would that we had the like of what hath been given unto korah! Lo! he is lord of rare good fortune.

(3) And korah, Pharaoh and Haman! Moses came unto them with clear proofs (of Allah's Sovereignty), but they were boastful in the land. And they were not winners (in the race).

(4) Unto Pharaoh and Haman and korah, but they said: A lying sorcerer!
