Father knows best is a sentence which helps to perform gender in front of a growing child. Every Child gets his surname in the name of his father. When we achieve something and take reward we are called by the names of our father but Holy Prophet P.B.U.H says; 'on the day of Judgement everyone will be called by the name of his/her mothers.' In India Delhi High court has passed an order that every child has the right to have his/her mother's name as surname.
