Take advice from others, Maintain personal hygiene & grooming habits

This hadith is about the importance of cutting one's hair. It was narrated by Wa'il bin Hujr that he went to the Prophet ﷺ with long hair and the Prophet ﷺ said that it was bad. He thought that the Prophet meant him, so he cut his hair and returned to him. The Prophet then clarified that he did not mean him but rather cutting one's hair is better than having long hair. This hadith teaches us about taking advice from others and also emphasizes on personal hygiene and grooming habits which are important for a healthy lifestyle. It also shows us how much attention the prophet paid to even small details like this in order to ensure people were living their best lives possible according to Islamic teachings.
