Calling someone a tyrant

Q 1: when may a specific person be called a tyrant? Who has the right to call someone as such? Finally, what is the ruling on such a label being repeated by the common people after being conveyed from its first teller?

A: A tyrant is an oppressive person. Such a description may only be ascribed to specific people by those who have sound knowledge and certain information about people who deserve to be called so.On the other hand, it is not permissible that the common people ascribe such a label to specific people as they are not entitled to issue a Shar`y (Islamic legal) ruling.
