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

(191) And make not your oaths a means of deception among yourselves, lest a foot should slip after being firmly planted, and you may have to taste the evil (punishment in this world) of having hindered (men) from the Path of Allah (i.e. Belief in the Oneness of Allah and His messenger, Muhammad صلى الله عليه و سلم), and yours will be a great torment (i.e. the Fire of Hell in the Hereafter).

(192) And verily, there had come unto them a messenger (Muhammad صلى الله عليه و سلم) from among themselves, but they denied him, so the torment overtook them while they were Zalimun (polytheists and wrong-doers).

(193) Verily, this Qur'an guides to that which is most just and right and gives glad tidings to the believers (in the Oneness of Allah and His messenger, Muhammad صلى الله عليه و سلم), who work deeds of righteousness, that they shall have a great reward (Paradise).

(194) Whoever goes right, then he goes right only for the benefit of his ownself. And whoever goes astray, then he goes astray to his own loss. No one laden with burdens can bear another's burden. And We never punish until We have sent a messenger (to give warning).

(195) (This was Our) Sunnah (rule or way) with the messengers We sent before you (O Muhammad صلى الله عليه و سلم), and you will not find any alteration in Our Sunnah (rule or way).

(196) "Or you have a house of Zukhruf (like silver and pure gold), or you ascend up into the sky, and even then we will put no faith in your ascension until you bring down for us a Book that we would read." Say (O Muhammad صلى الله عليه و سلم): "Glorified (and Exalted) be my Lord [(Allah) above all that evil they (polytheists) associate with Him]! Am I anything but a man, sent as a messenger?"

(197) And nothing prevented men from believing when the guidance came to them, except that they said: "Has Allah sent a man as (His) messenger?"

(198) Say: "If there were on the earth, angels walking about in peace and security, We should certainly have sent down for them from the heaven an angel as a messenger."

(199) And We send not the messengers except as givers of glad tidings and warners. But those who disbelieve, dispute with false argument, in order to refute the truth thereby. And they treat My Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), and that with which they are warned, as a jest and mockery!

(200) Do then those who disbelieved think that they can take My slaves [i.e., the angels, Allah's messengers, 'Îsa (Jesus), son of Maryam (Mary)] as Auliya' (lords, gods, protectors) besides Me? Verily, We have prepared Hell as an entertainment for the disbelievers (in the Oneness of Allah - Islamic Monotheism) .
