The focus of the silsila like the Chain of Authenticity is to trace the lineage of a Sufi order to Mohammad through his Companions: Ali bin Abi Talib (the primary link between Sufi orders and Mohammad), Abu Bakr, and Umar (three of the Four Righteously Guided Caliphs). When a Sufi order can be traced back to Mohammad through one of the three aforementioned Companions the lineage is called the Silsilat al-Dhahab (dhahab meaning gold) or the “Chain of Gold” (Golden Chain). In early Islamic history, gold was an extremely desired prize and was used for currency, to show wealth and power, and for scientific purposes including medicine.
