Follow in footsteps of predecessors without blindly following them; Strive for more knowledge before making decisions; Respect different opinions regarding religious matters etc..

This hadith is about fasting on the day of Arafah. It was narrated by Ibn Abi Najib from his father who said that when Ibn Umar was asked about fasting on this day, he replied that none of the four rightly guided caliphs - Prophet Muhammad, Abu Bakr, Umar and Uthman - ever fasted this day. He also added that he himself does not fast this day nor orders anyone to do so or forbids anyone from doing so either. This hadith teaches us to be humble in our religious practices and to follow in the footsteps of our predecessors without blindly following them as well as being open-minded towards different opinions regarding religious matters. We should also remember that we are all human beings with limited knowledge and wisdom; therefore we should always strive for more knowledge before making any decisions regarding religious matters or anything else for that matter.
