A sound discussion considers evidence, the actual question, and the audience’s understanding; its aim is to clarify truth. Once the primary goal becomes winning, gaining followers, or embarrassing another person, the discussion loses its educational character.
Case 1: A teacher corrects a misreading and explains the evidence: that is beneficial instruction.
Case 2: A student repeatedly asks questions merely to appear superior: that shows a defective aim.
Case 3: A learner accepts correction after discovering an error: this strengthens intellectual honesty.
The three expressions لِيُجَارِيَ، لِيُمَارِيَ، يَصْرِفَ describe different forms of the same problem: seeking status through knowledge.
