Hi ! What are you watching ?   It ’ s a program about islam . It ’ s very interesting .   Wow ! So many people ! Where are they and what are they doing ?   They are muslims on a pilgrimage to mecca . Muslims call this pilgrimage “ haj ” .   Why do they go there ?   Muslims believe that every man who is able should go on a haj at least once in his life . Mecca is the spiritual centre of the muslim faith .   When muslims pray , they face towards mecca .   That ’ s right . Unfortunately , so many people go on the haj each year that there are often stamped and people get killed .
