According to Nancy Lutfy, someone who has studied Islam for quite a while, many people appealed to Islam because they saw how this man "Muhammad", a profit of God, never gave up on what he believed. What he believed was what God had told him. He also was an accepting and caring to everyone, no matter what they did or who they were. By this, the people thought by listening to him was like him speaking the words of God giving them a good life. Basically Nancy is saying that because of Muhammad's acceptance to everyone and how nice he was that God must've been in him somehow. They believed that God was in him so that would mean he would be living a good life. Many people followed him because they believed Muhammad's teachings would lead them to a good life also. Muhammad's character told a lot about who he was which was part of the reason why so many people appealed to Islam.
