Treat people with justice and fairness regardless of their faith or beliefs ; Respect people's rights even if they are not Muslims ; Pay diya/blood money when someone has been wronged ; Protect those who live in an Islamic state regardless of their faith .

This hadith teaches us about the importance of justice and fairness in Islam. According to this hadith, Prophet Muhammad taught that if a Muslim harms a non-Muslim person or their property then they must pay diya or blood money as compensation. However, this diya should be half of what it would be if a Muslim was harmed by another Muslim. This shows us that even though Muslims and non-Muslims are different in terms of faith and beliefs, they should still be treated with justice and fairness according to Islamic teachings. Furthermore, this hadith also teaches us about the importance of protecting people who are not Muslims but live in an Islamic state as they have certain rights which must be respected by all citizens regardless of their faith or beliefs.
