During his first visit to the Holy Shrine of Imam Redha (PBUH), a 30-year-old Canadian named Jonathan Clark converted to Islam, selected Shiism as his sect, and assumed the name "Mohammad."

Concerning his acquaintance with Islam, Mohammad said: "The morals and behaviours of my classmate were truly remarkable. When I was talking to him about his religion, he called himself a Muslim, so I decided to study Islam because it seemed attractive to me."

He added, "When He told me that his religious book is called the Holy Quran, I read it carefully and discovered that this book had mentioned everything elegantly. After that, I read and studied more familiar books about Islam."
