Introduction There is a big difference between personality and character ethics, but many people do not have any idea on the reality of the outstanding difference between the two subjects. Personality temporary as it depends on the psychological environment that a person is exposed to, whereas character is permanent and it is not affected in any way by the psychological environment. However, character ethic, which ought to be dominant, is not always dominant in most people due to their strong personalities. Psychologists argue that this hypothesis underscores the main reason why many people are not successful and cannot influence the world. In the light of this realization, Prophet Muhammad, despite his physical challenging environment, had a strong character ethic that dominated his personality, which made him a legendary Muslim leader (Robinson 188). Brockopp (83) notes that Muslims believe that Muhammad was a prophet of God as well as a messenger, but he is assumed to have been stronger and more influential than all other prophets were. To the Muslim community, Muhammad is an influential icon just like Jesus is to the Christian community. He is believed to have been born in 570 CE and his real name is assumed to have been Abū al-Qāsim Muhammad in Arabic, which is transliterated as Muhammad. Even though God used many prophets to deliver messages to his people, Muhammad is believed to have been the last and the most influential, as evidenced by his initiation of the Quran writing. Non-Muslims refer to Muhammad as the founder of the Islamic religion, but Muslims believe that he is not the founder of the Islamic religion, but rather he was a follower because he too was an Islam. In addition, Muslims took him as a restorer of the unaltered faith of Adam, Abraham, and other prophets like Elijah and Jesus. According to Lapidus (78), Muhammad rose from humble beginnings to become a legendary leader of the Islamic religion just like Jesus in the case of Christian community. Influence of Muhammad’s Personality and Character Ethics Muhammad is strongly believed to have been born in about 570 CE, as there is no solid evidence of his birth date in the Quran or other books, in the Arabian city, Mecca. He was born to a poor family living in the desert and worst still lost his parents at a tender age. His uncle, Abu Talib, brought him up in the same city. At an early age, he portrayed a strong character ethic of independence and desire to do things his own way and that disposition pushed him into business. Despite being a young merchant, he was still a shepherd and looked after his uncle’s sheep and camels. At the age of twenty-five, Muhammad was already married and he was one of the wealthiest young men in Mecca. His character ethic of independence from other people’s normal way of doing things gave him a chance to retreat to the caves in the mountainous environment where he would carry out his periodic prayers. Other people that were close to him understood his personality and always allowed him to do things his own way, which illustrates that they admired his way of life and doing things since his young age and the reason he had a great multitude of followers (Brown 90). He continued to carry out his prayers in seclusion and at the age of forty, he first came across the first God’s revelation in his life. He continued to have the revelations for a long time, b
