Salah satu para intelektual dan ahli fikir barat yang menumpukan minatnya di atas peribadi atau personaliti Baginda ialah Michael Hart.
His first book was The 100: A Ranking of the Most Influential Persons in History, which has sold more than 500,000 copies and been translated into 15 languages. What mainly surprised readers in this book was the first person on Hart's list (Hart, 1992). Hart decided to choose Muhammad over Jesus or Moses. Hart attributes this to the fact that Muhammad was "supremely successful" in both the religious and secular realms. He also writes that Muhammad's role in the development of Islam is far more influential than Jesus's collaboration in the development of Christianity. He attributes the development of Christianity to St. Paul, who played a pivotal role in the dissemination of Christianity.
Mereka benar-benar mengkaji kejayaan Rasulullah. Adakah dalam hati kita ada cinta tulus kepada Rasulullah dan benar2 mengenalinya?
