“I was a member of Waqifa sect and I wen to Hajj with the same belief. When I arrived in Makka an idea began to prick my chest. I got hold of al-Multazam (the wall next to the door of Ka‘ba) and said, “O Lord, You know what I ask for and my intention. Guide me to the best of the religions. It then occurred to me to see al-Rida (a.s.). I went to the city of Madina and stood in front of his door and said to his slave, ‘Tell your master that a man from Iraq is at the door.’” He has said that I heard his voice saying, “O ‘Abdallah ibn Mughira, come in.” I then went inside and when he looked at me he said, “Allah has answered your prayer and has guided you to His religion.” I then said, “I testify that you possess Divine Authority and you are the trustee of Allah over His creatures.” :
