Does the common biography of the great prophet Mohammed reveal his real life and history? We always have to ask this question seriously because we cannot understand the religion correctly unless we recognizing the prophet's real life. I mean the prophet's history and life interpret and explain the real religion. Therefor God commands all muslims to follow the prophet in their life, he says (وما آتاكم الرسول فخذوه وما نهاكم عنه فانتهوا). Also the prophet instructs them to do as he did in religion teachings like prayer and hajj, so he says (صلوا كما رأيتموني أصلي)، and (خذوا عني مناسككم). We maybe can say the prophet's common biography at this time is confused, because several things have caused losing the real information about the events that happened during the prophet's life, like: 1- The lying in writing and imparting the events and information. A lot of writers, speakers, preachers and news-mongers were lying in imparting the information and the real events. we will not be able to know the true prophet's biography as long as that information is not revised. 2- The mistakes that are present in muslims' behaviors. None muslims didn't see the prophet and most of them didn't read his life, but they can recognize it through his followers -I mean all muslims. The real life of prophet will not be introduced correctly If muslims' behaviors are wrong. So we have to revise that information, and try to do everything correctly, and deal with all people politely to be able to bring the prophet image closer to people everywhere
