Hey stupid monkey, why have you come to Lanka

Story Play (Attakkatha): 
Hearing what Vibheeshana said,  Ravana, in his court tells a fearless Hanuman in a deafening voice.

Hey stupid monkey,  why have you come 

to Lanka and killed my guards without  any hesitation?

I am Ravana, who makes my enemies  weep. Is it without knowing this, that you did all this?
