When the Prophet received his first revelation from Angel Jibril, he was scared and went to see Waraqah to tell him what had happened. Waraqah listened to the Prophet's story and recognized that he was receiving revelations from God, just like the prophets before him. He told the Prophet that he was a prophet of God and encouraged him to continue with his mission.
