Answer :
The Holy Land is important for all three faiths because each faith sites locations within the Holy Land as important to their faith. For Muslims the Dome of the Rock today covers the place where the Prophet Muhammad ascended into heaven to speak with god. For Jews the same location called the "Temple Mount" is the place where they believe their famous first and second temples were built. And Christians believe that Jesus was born in Bethlehem and lived in Nazareth both locations are within the Holy Land. These are a few of the reasons except many others exist as well including numerous other important holy sites.
