Be mindful of past practices when making decisions in life today; strive to make sure your decisions are fair and just for all involved parties; take responsibility for your actions; respect other people's beliefs even if they differ from yours; pay taxes or tributes if required by law or custom .

This hadith is about how Umar ibn al Khattab imposed a tenth on the Nabateans. The tenth was something that was taken from them during the jahiliyya, which is an Arabic term for pre-Islamic times. This means that before Islam, people were taking a tenth of their possessions as taxes or tribute to their rulers. When Umar became ruler of this region, he decided to continue this practice and impose it on them as well. This hadith teaches us that we should be mindful of our past practices and traditions when making decisions in our lives today. We should also be aware of how our decisions may affect others and strive to make sure they are fair and just for all involved parties.
