This hadith discusses the permissibility of eating fish caught by magians and anything that is dead in the sea. The people from al-Jar asked Marwan ibn al-Hakam about eating what was cast up by the sea and he said there was no harm in it. He then suggested they ask Zayd ibn Thabit and Abu Hurayra for their opinion on this matter as well. When they did so both of them agreed with Marwan's opinion that there was no harm in it. Malik then added that if it is eaten when it is dead there would be no harm either regardless of who catches it. This hadith teaches us to be mindful of what we consume as Muslims as well as being respectful towards other religions or beliefs even if we do not agree with them ourselves. We should also seek out knowledge from reliable sources before making decisions or forming opinions on matters such as these so we can make sure our actions are within Islamic guidelines while still being respectful towards others beliefs or practices at the same time.
