Then Ráma answered. “Hatred dies When low in dust the foeman lies. Now triumph bids the conflict cease, And knits us in the bonds of peace. Let funeral rites be duly paid. And be it mine thy toil to aid.”

In plain words: Rama answers that hatred ends when the enemy is dead, and now the victory brings peace between them. He tells Vibhishana to hold the funeral properly and offers to help.
