For those who deny that Prophet Muhammad peace be upon him was a messenger, lets study his life a bit and find out what was his purpose then. First of all we all agree that Prophet Muhammad (S.A.W) was an unlettered man and he was know as “Al-Amin”1 meaning “Faithful”, “trust worthy”, its mention in the Quran “Those who follow the messenger, the unlettered Prophet….” (Quran chapter 7 verse 157) If he was a lettered man not a single Arab would follow him during his time, since the Quran clearly mentions that he was unlettered.
During his time one of the false allegation made was that he was a made man, how can a made man make a complete code of life, ethics and how to behave, how to treat our neighbors, how to deal with our wife and children’s, how inheritance must be shared, jurisprudence, he covers all the aspects of life, how in the world a mad man can do all this.
If he really was very intelligent and was lying why would he stand up for prayer every single night till his feet would swallow “Narated By Al-Mughira : The Prophet used to stand (in the prayer) or pray till both his feet or legs swelled. He was asked why (he offered such an unbearable prayer) and he said, "should I not be a thankful slave." (sahih bukahri book 21:230).
In the Quran it criticizes some actions of the prophet and warns the messenger, its mention in the Quran “(The Prophet) frowned and turned away, Because there came to him the blind man (interrupting). But what could tell thee but that perchance he might grow (in spiritual understanding)? Or that he might receive admonition, and the teaching might profit him?” (Quran chapter 80 verse 2-4) Also its mention in the Quran “And if the messenger were to invent any sayings in Our name, We should certainly seize him by his right hand, And We should certainly then cut off the artery of his heart:” (Quran chapter 69 verse 44-46) This is indeed a clear warning and it does not fit to the psychology of a man to criticize and warn himself in a book he write. Also we know that the prophet lived a life of the lowest and he use to suffer in hunger for days.
The Arabs at that time gave him all kinds of dealings, what ever amount of wealth or position but under the condition that he must stop this preaching but he refused and continued, put his life under threat, suffered prosecution and was sent out from his own city. So for sure he cannot be a liar and he cannot be a made man since he thought a complete code of life. He was a states man, husband, military leader, father, judge, slave and a worshiper of God. So the only conclusion we can make is that he was indeed a messenger from God just like Abraham, Moses and Jesus peace be upon them all and he was the last and final messenger.
Say: "O men! I am sent unto you all, as the Messenger of Allah, to Whom belongeth the dominion of the heavens and the earth: there is no god but He: it is He That giveth both life and death. So believe in Allah and His Messenger, the Unlettered Prophet, who believeth in Allah and His words: follow him that (so) ye may be guided." (Quran chapter 7 verse 158)
