The word(s) "warner" appears 58 time(s) in 54 verse(s) in Quran in Mohsin Khan translation.

(31) You (O Muhammad صلى الله عليه وسلم) are only a warner (i.e. your duty is to convey Allah's Message to mankind but the guidance is Allah's).

(32) Verily We have sent you with the truth, a bearer of glad tidings and a warner. And there never was a nation but a warner had passed among them.

(33) Therein they will cry: "Our Lord! Bring us out, we shall do righteous good deeds, not (the evil deeds) that we used to do." (Allah will reply): "Did We not give you lives long enough, so that whosoever would receive admonition could receive it? And the warner came to you. So taste you (the evil of your deeds). For the Zalimun (polytheists and wrong-doers) there is no helper."

(34) And they swore by Allah their most binding oath that if a warner came to them, they would be more guided than any of the nations (before them); yet when a warner (Muhammad صلى الله عليه وسلم) came to them, it increased in them nothing but flight (from the truth)

(35) And indeed We sent among them warners (Messengers);

(36) And they (Arab pagans) wonder that a warner (Prophet Muhammad صلى الله عليه وسلم) has come to them from among themselves. And the disbelievers say: "This (Prophet Muhammad صلى الله عليه وسلم) is a sorcerer, a liar.

(37) Say (O Muhammad صلى الله عليه وسلم): "I am only a warner and there is no Ilah (God) except Allah (none has the right to be worshipped but Allah) the One, the Irresistible,

(38) "Only this has been revealed to me, that I am a plain warner."

(39) And similarly, We sent not a warner before you (O Muhammad صلى الله عليه و سلم) to any town (people) but the luxurious ones among them said: "We found our fathers following a certain way and religion, and we will indeed follow their footsteps."

(40) (The warner) said: "Even if I bring you better guidance than that which you found your fathers following?" They said: "Verily, we disbelieve in that with which you have been sent."
