Perform rituals thoroughly and pay attention to detail while doing so.

This hadith is about the method of ablution that was practiced by the Prophet Muhammad (PBUH). Ablution is a ritual washing performed by Muslims before prayer or other acts that require physical and spiritual purity. According to this hadith, when performing ablution, the Prophet would rub both sides of his face with wet hands and then run his fingers through his beard from beneath. This action was done in order to ensure that all parts of the body were washed properly during ablution. It teaches us that we should be thorough in our religious practices and pay attention to even small details so as not to miss any part while performing rituals such as ablution.
