Treat everyone with respect and kindness regardless of their social status or position in life.

This hadith teaches us about the importance of justice and mercy. It was narrated by Ibn 'Umar, who was one of the companions of Prophet Muhammad ﷺ. In this hadith, it is mentioned that if a slave is beaten or slapped on the face for something he has not done, then his master must set him free as an expiation. This shows us how important it is to be just and merciful towards those who are weaker than us in society. We should never take advantage of our power over others and should always strive to treat everyone with respect and kindness regardless of their social status or position in life.
