The word(s) "messenger" appears 501 time(s) in 433 verse(s) in Quran in Mohsin Khan translation.

(321) This is so! And for the Taghun (transgressors, the disobedient to Allah and His messenger - disbelievers in the Oneness of Allah, criminals) will be an evil final return (Fire).

(322) And when Allah Alone is mentioned, the hearts of those who believe not in the Hereafter are filled with disgust (from the Oneness of Allah توحيد الله) and when those (whom they obey or worship) besides Him [like all false deities other than Allah, - it may be a messenger, an angel, a pious man, a jinni, or any other creature even idols, graves of religious people, saints, priests, monks and others.] are mentioned, behold, they rejoice!

(323) And indeed it has been revealed to you (O Muhammad صلى الله عليه وسلم), as it was to those (Allah's messengers) before you: "If you join others in worship with Allah, (then) surely (all) your deeds will be in vain, and you will certainly be among the losers."

(324) And those who disbelieved will be driven to Hell in groups till, when they reach it, the gates thereof will be opened (suddenly like a prison at the arrival of the prisoners). And its keepers will say, "Did not the messengers come to you from yourselves, reciting to you the Verses of your Lord, and warning you of the Meeting of this Day of yours?" They will say: "Yes, but the Word of torment has been justified against the disbelievers!"

(325) The people of Nuh (Noah) and the Confederates after them denied (their messengers) before these; and every (disbelieving) nation plotted against their messenger to seize him, and disputed by means of falsehood to refute therewith the truth. So I seized them (with punishment), and how (terrible) was My punishment!

(326) That was because there came to them their messengers with clear evidence (proofs and signs) but they disbelieved (in them). So Allah seized them (with punishment). Verily He is All-Strong, Severe in punishment.

(327) And indeed Yusuf (Joseph) did come to you, in times gone by, with clear signs, but you ceased not to doubt in that which he did bring to you: till when he died you said: "No messenger will Allah send after him." Thus Allah leaves astray him who is a Musrif (a polytheist, an oppressor, a criminal, sinner who commit great sins) and a Murtab (one who doubts Allah's Warning and His Oneness).

(328) They will say: "Did there not come to you, your messengers with (clear) evidence (and signs)?" They will say: "Yes." They will reply: "Then call (as you like)! And the invocation of the disbelievers is nothing but in vain (as it will not be answered by Allah)!"

(329) Verily, We will indeed make victorious Our messengers and those who believe (in the Oneness of Allah - Islamic Monotheism) in this world's life and on the Day when the witnesses will stand forth, (i.e. Day of Resurrection) -

(330) Verily those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, without any authority having come to them, there is nothing else in their breasts except pride [to accept you (Muhammad صلى الله عليه وسلم) as a messenger of Allah and to obey you] . They will never have it (i.e. Prophethood which Allah has bestowed upon you). So seek refuge in Allah (O Muhammad صلى الله عليه وسلم from the arrogants). Verily, it is He Who is the All-Hearer, the All-Seer.
