Respect other religions and cultures; Be open-minded; Change habits if necessary

This hadith is about how Prophet Muhammad's hairstyle changed over time. Initially, he followed the same style as the People of the Book, which was to let their hair hang down. However, later on he decided to part his hair instead. This shows us that even though Prophet Muhammad was a messenger from Allah and received divine revelations, he still respected other religions and cultures and tried to follow them in certain matters when there were no clear instructions from Allah. It also teaches us that we should be open-minded and willing to change our habits if necessary for our own benefit or for others'.
