Strive for justice and fairness in our society at all times .

This hadith discusses the concept of retaliation in Islam, which is known as qisas. It states that if someone kills a relative of another person, then they must either pay diyya or face death themselves. Diyya is a form of compensation paid by the killer to the family of the victim in order to make up for their loss. This hadith also emphasizes that justice should be served and that no one should be allowed to get away with murder without facing consequences for their actions. It teaches us that we must always strive for justice and fairness in our society, even when it comes to matters such as murder and killing. Furthermore, this hadith also serves as an example of how Prophet Muhammad (PBUH) was able to bring peace and stability into society by introducing laws which were fair yet firm enough to ensure justice was served at all times.
