Custodians of the Faith
The Promised Messiah (as) states:
“It is vital to believe that Siddiq-e-Akbar (ra) [Hazrat Abu Bakr Siddiq (ra)], Hazrat Farooq-e-Umar (ra) [Hazrat Umar Farooq (ra)], Hazrat Dhun-Nurain (ra) [Hazrat Uthman (ra)] and Hazrat Ali Murtaza (ra) were all the custodians of the faith.”
