Holiest of relics 

The veneration of relics is popular across South Asia. Memorials on the models of tombs have been built over many of these relics. Shrines known as Qadam Rasul (Footprints of Prophet Muhammad PBUH) are found in Delhi, Awadh, Lucknow and many other Indian cities. According to Annemarie Schimmel, the relic of a footprint of the Prophet (PBUH) was preserved from early times and special Qadam Rasul sanctuaries were erected for it. Hairs of the Holy Prophet (PBUH), or pieces from his shirt, as well as relics of Imams Ali (A.S.) and Hussain (RA) are preserved in various places from Kashmir to Sindh and the Deccan.
