I was one of the Waqafites and went on a pilgrimage to Mecca having the same belief. Once I reached Mecca, I wondered whether my belief was correct or not. Then I sought refuge next to the al-Moltazam wall and said, ‘O my God! You know what I want and wish for. Please guide me to the best religion.’ Then it occurred to me to visit Ar-Ridha’ (a.s.). I went to Medina, stood at the door of Ar-Ridha’’s (a.s.) house and told his servant, ‘Go and tell your Master that a man from Iraq is waiting at the door and wants permission to enter.’ I heard Ar-Ridha’’s (a.s.) voice from within the house saying, ‘O Abdullah ibn al-Mogheera! Come in.’ I entered. When Ar-Ridha’ (a.s.) saw me, he (a.s.) said, ‘God accepted your prayer and guided you towards His Religion.’ I said, ‘I bear witness that you are the Proof of God and the Trustee of God for His creatures.’”
