Follow the example set by Prophet Muhammad . Make decisions which are beneficial for both ourselves and those who come after us .

This hadith is about how 'Umar ibn al-Khattab, one of the companions of Prophet Muhammad, wanted to divide conquered towns in a similar way that Prophet Muhammad divided Khaibar. He said that if it weren't for future generations of Muslims, he would not have taken over any town but instead would have divided it. This shows us that 'Umar was very mindful and considerate towards future generations and wanted them to benefit from his actions. He also showed us how important it is to follow the example set by Prophet Muhammad and use it as a guide for our own actions. By doing this, we can ensure that our decisions are beneficial for both ourselves and those who come after us.
