Many Muslims, especially in South Asia, believe that whenever Muhammad trod on a rock his foot left an imprint. Some pilgrims to Mecca in Saudi Arabia have recovered stones believed to bear such an imprint. However, this belief does not sanctioned by the orthodox religious leadership. Similar objects having been claimed as being the personal effects of Muhammad are preserved in shrines across the Middle East and South Asia. A notable example includes the Hazratbal mosque in Jammu and Kashmir, where a hair of Muhammad is supposedly preserved.
