Obey God’s orders, Respect religious laws/rules/guidelines

This hadith is about the Prophet Muhammad's ﷺ curse on the Jews. The Prophet ﷺ cursed them because they disobeyed Allah's orders and sold liquefied fat, which was forbidden to them. This hadith teaches us that we should always obey Allah's orders and not do anything that He has prohibited us from doing. It also teaches us that we should be careful of our actions and not take any action that could lead to a punishment from Allah. We should also remember that disobedience of Allah will result in His wrath and punishment, so it is important to stay away from any kind of disobedience or sinning.
