After leaving Damascus, they saw a huge crowd on the way to Medina. On enquiring, it was known that a crowd of Christian priests and monks had assembled to have a glimpse of a great saint. When the saint's eyes fell on Muhammad al-Bakir, he asked him whether he was one of them or not. Imam replied that he belonged to the blessed nation of Prophet Muhammad. The saint asked him many questions, which were replied to him. Muhammad al-Bakir told him that, "The religion of Jesus Christ is true, but it is too old. While the religion of Muhammad is fresh. As the fresh food is essential for the body, so is the fresh religion for the soul." The tradition has it that it deeply impressed the saint, who is said to have embraced Islam.
