  Ali is the common source of mystical and spiritual currents within both Sunni and Shia sects of Islam. In particular, Ali is the spiritual head of some Sufi movements, for Sufis believe that Ali inherited from Muhammad his esoteric knowledge and saintly authority, which guide believers on their journey toward God. Nearly all Sufi orders trace their lineage to Muhammad through Ali, an exception being the Naqshbandis, who reach Muhammad through Abu Bakr.
