Understand your religion through reading & studying both Quran & other related documents . Pay diyah or ransom if you commit murder . Retaliate against those who kill Muslims regardless of their religion or beliefs .

This hadith was narrated by Abu Juhaifah who asked 'Ali about something from the Messenger of Allah apart from the Quran. 'Ali said that he only has understanding that Allah helps people to acquire from the Quran or what is written in documents. When asked what is written in documents, 'Ali said it includes diyah, ransom for prisoners, and that a muslim should be killed in retaliation for a kafir. This hadith teaches us to understand our religion through reading and studying both the Quran as well as other documents related to it. It also teaches us about justice; if someone kills another person then they must pay diyah or ransom for their crime according to Islamic law. Lastly, this hadith also teaches us about equality; if someone kills a Muslim then they must be killed in return regardless of their religion or beliefs.
