The word(s) "warn" appears 127 time(s) in 113 verse(s) in Quran in Muhammad Habib Shakir translation.

(71) Naught is revealed to me save that I am a plain warner.

(72) And those who disbelieve shall be driven to hell in companies; until, when they come to it, its doors shall be opened, and the keepers of it shall say to them: Did not there come to you apostles from among you reciting to you the communications of your Lord and warning you of the meeting of this day of yours? They shall say: Yea! But the sentence of punishment was due against the unbelievers.

(73) Possessor of the highest rank, Lord of power: He makes the inspiration to light by His command upon whom He pleases of His servants, that he may warn (men) of the day of meeting.

(74) And warn them of the day that draws near, when hearts shall rise up to the throats, grieving inwardly; the unjust shall not have any compassionate friend nor any intercessor who should be obeyed.

(75) A herald of good news and a warner, but most of them turn aside so they hear not.

(76) But if they turn aside, then say: I have warned you of a scourge like the scourge of Ad and Samood.

(77) And thus have We revealed to you an Arabic Quran, that you may warn the mother city and those around it, and that you may give warning of the day of gathering together wherein is no doubt; a party shall be in the garden and (another) party in the burning fire.

(78) And thus, We did not send before you any warner in a town, but those who led easy lives in it said: Surely we found our fathers on a course, and surely we are followers of their footsteps.

(79) (The warner) said: What! even if I bring to you a better guide than that on which you found your fathers? They said: Surely we are unbelievers in that with which you are sent.

(80) Surely We revealed it on a blessed night surely We are ever warning--
