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

(21) How shall Allah guide a people who disbelieved after their belief and after they bore witness that the messenger (Muhammad صلى الله عليه وسلم) is true and after clear proofs had come unto them? And Allah guides not the people who are Zalimun (polytheists and wrong-doers).

(22) Say: "O people of the Scripture (Jews and Christians)! Why do you stop those who have believed, from the Path of Allah, seeking to make it seem crooked, while you (yourselves) are witnesses [to Muhammad صلى الله عليه وسلم as a messenger of Allah and Islam (Allah's religion, i.e. to worship none but Him Alone)]? And Allah is not unaware of what you do."

(23) And how would you disbelieve, while unto you are recited the Verses of Allah, and among you is His messenger (Muhammad صلى الله عليه وسلم)? And whoever holds firmly to Allah, (i.e. follows Islam - Allah's Religion, and obeys all that Allah has ordered, practically), then he is indeed guided to the Right Path.

(24) Surely, those who reject Faith (disbelieve in Allah and in Muhammad صلى الله عليه وسلم) as being Allah's messenger and in all that which he صلى الله عليه وسلم has brought from Allah), neither their properties, nor their offspring will avail them aught against Allah. They are the dwellers of the Fire, therein they will abide. (Tafsir At-Tabari).

(25) And obey Allah and the messenger (Muhammad صلى الله عليه وسلم) that you may obtain mercy.

(26) Many similar ways (and mishaps of life) were faced by nations (believers and disbelievers) that have passed away before you (as you have faced in the battle of Uhud), so travel through the earth, and see what was the end of those who disbelieved (in the Oneness of Allah, and disobeyed Him and His messengers).

(27) Muhammad (صلى الله عليه وسلم) is no more than a messenger, and indeed (many) messengers have passed away before him. If he dies or is killed, will you then turn back on your heels (as disbelievers)? And he who turns back on his heels, not the least harm will he do to Allah; and Allah will give reward to those who are grateful.

(28) (And remember) when you ran away (dreadfully) without even casting a side glance at anyone, and the messenger (Muhammad صلى الله عليه وسلم) was in your rear calling you back. There did Allah give you one distress after another by way of requital to teach you not to grieve for that which had escaped you, nor for that which had befallen you. And Allah is Well-Aware of all that you do.

(29) Indeed Allah conferred a great favour on the believers when He sent among them a messenger (Muhammad صلى الله عليه وسلم) from among themselves, reciting unto them His Verses (the Qur'an), and purifying them (from sins by their following him), and instructing them (in) the Book (the Qur'an) and Al-Hikmah [the wisdom and the Sunnah of the Prophet صلى الله عليه وسلم (i.e. his legal ways, statements, acts of worship)], while before that they had been in manifest error.

(30) Those who answered (the Call of) Allah and the messenger (Muhammad صلى الله عليه وسلم) after being wounded; for those of them who did good deeds and feared Allah, there is a great reward.
