Cultural Shock: Culture shock is the personal disorientation a person may feel when experiencing an unfamiliar way of life due to immigration or a visit to a new country, or to a move between social environments, also a simple travel to another type of life.
To avoid cultural Shock, Newborn religion adopt some method/culture of existing religion. Many Islamic practices were existing practices. Be it skull cap, Khatna, Halal eating, Name of your god, Beard, Way of worship etc.
The newborn religion copy the fables as well. Be it Noah the ark, Adam-eve etc..
@<u><a href="http://www.defence.pk/forums/member.php?u=2181" target="_blank">Muhammad</a></u> last prophet: Who said?? He himself and his few followers. Is there are historical documents (Independent Historian) or archeological evidence available for it? Sunni Muslims believe that he was last prophet, Shia or Ahmedi don't. Or may be Muhammad spread this word "Last prophet" so that there must not another Islam like religion take birth. (to avoid division of Islam)
