Follow Islamic teachings instead of worldly practices; strive for piety; differentiate yourself from non believers in terms of beliefs and practices; do not dye your hair if you are a Muslim.

In this hadith, the Prophet Muhammad (SAW) is advising Muslims to differentiate themselves from non-Muslims, specifically Jews and Christians. He advises that one way of doing this is by not dyeing their hair, as it was a practice of the non-believers at the time. This hadith teaches us that we should strive to be different in our beliefs and practices than those who do not follow Islam. We should also remember that Allah has given us guidance on how to live our lives in accordance with His teachings, so we should strive to follow them instead of following what others are doing around us.
