The word(s) "apostle" appears 368 time(s) in 325 verse(s) in Quran in Muhammad Habib Shakir translation.

(271) He it is Who sent His apostle with the guidance and the true religion that He may make it prevail over all the religions; and Allah is enough for a witness.

(272) Muhammad is the apostle of Allah, and those with him are firm of heart against the unbelievers, compassionate among themselves; you will see them bowing down, prostrating themselves, seeking grace from Allah and pleasure; their marks are in their faces because of the effect of prostration; that is their description in the Taurat and their description in the Injeel; like as seed-produce that puts forth its sprout, then strengthens it, so it becomes stout and stands firmly on its stem, delighting the sowers that He may enrage the unbelievers on account of them; Allah has promised those among them who believe and do good, forgiveness and a great reward.

(273) O you who believe! be not forward in the presence of Allah and His apostle, and be careful of (your duty to) Allah; surely Allah is Hearing, Knowing.

(274) Surely those who lower their voices before Allah's apostle are they whose hearts Allah has proved for guarding (against evil); they shall have forgiveness and a great reward.

(275) And know that among you is Allah's apostle; should he obey you in many a matter, you would surely fall into distress, but Allah has endeared the faith to you and has made it seemly in your hearts, and He has made hateful to you unbelief and transgression and disobedience; these it is that are the followers of a right way.

(276) The dwellers of the desert say: We believe. Say: You do not believe but say, We submit; and faith has not yet entered into your hearts; and if you obey Allah and His apostle, He will not diminish aught of your deeds; surely Allah is Forgiving, Merciful.

(277) The believers are only those who believe in Allah and His apostle then they doubt not and struggle hard with their wealth and their lives in the way of Allah; they are the truthful ones.

(278) Qaf. I swear by the glorious Quran (that Muhammad is the apostle of Allah)

(279) And the dwellers of the grove and the people of Tuba; all rejected the apostles, so My threat came to pass.

(280) He said: What is your affair then, O apostles!
