Obey God’s commands .

This hadith is about how the Prophet Muhammad ﷺ cursed the Jews for disobeying Allah's orders. In this hadith, it is mentioned that when Allah forbade them to eat the fat of animals, they melted it and sold it, and utilized its price. This shows that they disobeyed what Allah commanded them to do and instead used their own judgement which was wrong. This teaches us that we should always obey what Allah has commanded us to do even if we don't understand why He has asked us to do something because He knows best. We should also not use our own judgement in matters related to religion as this can lead us astray from His path.
