A prophet is one who has been selected to represent God on earth. When God chooses a human being as His messenger, His angel comes to him to inform him of this selection. In this way, he is left in no doubt that he is indeed God’s messenger. Afterwards, God sends him His teachings through the angel so that he may inform all human beings of God’s will. The prophet is an intermediary between God and man. He takes from God His message and conveys it to human beings.
God has bestowed human beings with reason but, through reason alone, an individual cannot understand the deeper realities of the present life. So far as God and the world Hereafter are concerned, this is totally related to the invisible world and as such, these things are beyond human reason and understanding. What the prophet does is fulfil this need of every individual. The Prophet informs a person of the realities of life, and of the world Hereafter. In this way, he enables people to plan their life in the full light of divine knowledge.
From the time that people inhabited this world, the prophets started arriving in every age. They told humans of God’s will but, there are no authentic records of the teachings of the prophets of ancient times. The later circumstances failed to authenticate their personalities as factually historical and their books also suffered the same fate.
The Quran records the history of the prophets. It refers to more than two dozen prophets of different times and different races. God sent every prophet with the same message, but in different places and situations. In this sense, all the prophets are equal; every prophet is a source of guidance.
Finally, God chose the Prophet Muhammad as His Messenger. He was born at a time when world history had begun to be put on record. Subsequently, with the invention of the printing press, he became widely acknowledged as a historically established figure, and the Book divinely revealed to him, was preserved for all eternity. Ultimately, there was no possibility that any changes could be made in this divine book he had brought to the world. The Prophet Muhammad was the final messenger to humanity. No prophet will come after him.
