Strive for knowledge and understanding.

This hadith explains a verse from the Quran, which states that those who do not understand are considered to be the worst of beasts in Allah's sight. The people referred to here were some persons from a tribe called Bani 'Abd-Addar. This hadith teaches us that understanding is key and it is important for us to strive for knowledge and understanding so we can stay away from ignorance and foolishness. It also teaches us about humility, as even if we think we know something, there will always be someone else with more knowledge than us. We should never forget this lesson and always strive for more knowledge so we can become better people in Allah's eyes.
