Original story - Hanumana fly across the sea and reached Sri Lanka. There the soldiers of Ravana caught hold of him and put his tail on fire. He used that fire and spread across whole Lanka and burned down Ravana's kingdom
Re-telling from Ravana's point of view
Hanuman was a miscreant. I did not permit him to come to my kingdom. He illegally entered in my kingdom. When my soldiers caught hold of him and present him in the court for trial, I ordered to put his tail on fire as per the rule of law. I did not want to take his life or hurt him severely rather wanted to teach him a lesson. But he was such a trespasser that he went on to burn whole of my kingdom. I will take revenge from him at any cost.
