Islam rests upon two key beliefs. The first of these is belief in a single God, Allah, whose power and authority is completely unparalleled. The second is belief in Muhammad as Allah's final and greatest messenger. In order to become a Muslim, one must recite the Shahada. This is a declaration of acceptance of the two beliefs discussed above. If somebody has an issue with either, they cannot make the Shahada, meaning they cannot become a Muslim. Much has been written about the existence (or lack thereof) of Allah. Hundreds upon thousands of words have been produced claiming to either prove or disprove His existence. Less attention has been given to Muhammad. Unlike with many earlier prophets, secular historians agree that Muhammad certainly existed. But was Muhammad truly a prophet or was he the trouble making charlatan his rivals made him out to be? We, of course, hold steadfastly to the belief that Muhammad was the ultimate Messenger of Allah and that the Quran was revealed to him from the Heavens. In this article, we're going to be discussing just why we believe what we believe. Here are ten proofs Muhammad was a prophet.
