Criticism should be made out of friendship, not animosity
Being critical is a cordial course of action, not a hostile one. When you criticize someone, it is a cordial course of action: “Believers act as a mirror to other believers [Tohaf al-Oqul, page 173].” This means that you find and express the flaws and weaknesses that exist on the other side. --This is a good thing. So, criticism should be made. Sometimes, criticism should be made on a public level as well. We do not always believe that criticism should be made secretly. Sometimes, it should be public; but, if we criticize in a way that the hearts of our audience are torn apart, or they say to themselves: “everything is ruined, we are done,”--this is unacceptable. We sometimes make mistakes in the way that we voice our criticisms and we work like this.
