Use water to clean your nose when performing wudhu.

The hadith narrated by Abu Hurairah teaches us the importance of cleanliness during wudu, which is a ritual washing performed by Muslims before prayer. According to the hadith, we should use water to clean our noses when performing wudu. This is important because it helps us maintain physical and spiritual purity before prayer. It also reminds us that we should strive for cleanliness in all aspects of life, not just during religious rituals. Additionally, this hadith encourages us to take care of our bodies and keep them clean at all times as a sign of respect for Allah's creation.
