Questioned by Ravana's minister, Hanuman answered that he was indeed a monkey, come to Lanka as Rama's envoy to accomplish his commands and to behold Ravana, and he told the story of Rama up till then, and gave Ravana sound advice, to save his life by surrendering Sita.
Ravana was furious and would have Hanuman slain, but the counsellors reminded him that the punishment of death could not justly be inflicted upon one who named himself an envoy. Then Ravana cast about for a fitting penalty, and bethought him to set Hanuman's tail afire.
