When Ravana in his rage decreed the death of Hanuman, Vibhishana in his wisdom begged to differ. He tried to politely impress upon him that great kings did not put their envoys to death, since royal tradition and the rules of righteousness forbade such acts. "How could you, a great scholar display such anger in your court? Was it not a futile effort," said Vibhishna. His counsel angered Ravana even more who countered, "Killing a sinner is not a sin. I shall slay this wretched Vanara!" But Vibhishana, subduer of foes pleaded, "Listen Ravana the wise have declared that at no time or place can an emissary be slain. This creature has no doubt committed terrible offences, chastise him but do not kill him. Many are the ways of punishment prescribed in sastras for emissaries. Tonsuring, maiming, flogging or branding is permitted, but death certainly is not. How can you, who can discriminate between right and wrong fall prey to your passions? Do the brave not master their anger? Of what use is the killing of this vanara? Kill them who sent him. This messenger is the only one who can lead the arrogant princes to Lanka and into war with you.If you put him to death it will only lead to your infamy. Capture Rama and Lakshmana and it will bring you fame. Your soldiers are legion and their battle skills have no equal, send some of them to imprison your enemies and prove your might to the world". Ravana finally suppressed his anger. Though he suspected Hanuman to be the very embodiment of the effulgence of Visnu and furious about it, he decided to heed Vibhishana.
