What are the details of the Prophet Muhammad's (peace be upon him) life during the period between the ages of eight and twenty-five, in order to refute the claims of those who allege that he received knowledge from the monk Bahira?

The Christian assertion that the Prophet, peace be upon him, met with the monk Bahira and learned from him is false for the following reasons: The Prophet met Bahira only once, as a child, and did not receive any knowledge from him. His journeys to Syria were only twice. Bahira himself foretold the prophethood of the Prophet, peace be upon him, so it is inconceivable that he would have been his teacher. Furthermore, the corrupted nature of Bahira's religion could not have been the source of the Noble Qur'an and its guidance. Had this accusation been true, the Prophet's own people, who were the most eager to discredit him, would have adopted it. Instead, they accused him of learning from a non-Arab who did not speak Arabic well.
