Criticism often appears on everyday conversation with others. It is usually used to warn or advise people for their habit, act and behavior.

An Islamic scholar, Professor Murad bin Ahmad al-Qudsi, once said that people could not utter every criticism they had in mind. The best criticism to be delivered are those leading to goodness and full of positive spirit. Meanwhile, destructive criticism must be avoided.

Destructive criticism is such as attacking someone personally for his/her physical disability. Other indicator of destructive criticism are evaluating someone negatively without any firm evidence and insulting someone without objective and proportional view. Such criticism can be seen from the scale of objectivity.

Professor Murad said the criticism emerged due to some factors, such as envy and spite, pushed by anger. He admitted that it was not easy to turn down the emotion.
