Respect rules & regulations , Seek permission from elders before taking major decisions in life , Listen to wise counsel of experienced people .

This hadith is about a young man named Ibn Umar who wanted to join the army of Prophet Muhammad. When he was fourteen years old, the Prophet did not permit him to do so. However, when he turned fifteen, the Prophet allowed him to join. This hadith teaches us that there are certain age requirements for joining an army and that it is important for children and young adults to respect these rules and regulations set by their elders or leaders. It also teaches us that we should always seek permission from our elders before taking any major decisions in life as they have more experience than us and can guide us better in making wise choices.
