Perform ablution properly before prayer

This hadith speaks about the power of ablution or wudu in Islam. It is a ritual that Muslims perform before they pray and it involves washing certain parts of the body such as the hands, face and feet. According to this hadith, if one performs wudu properly then their sins will be cleansed from them even from under their nails. This shows how important it is for Muslims to perform wudu correctly in order to purify themselves spiritually and physically before prayer. It also teaches us that we should strive for purity in all aspects of our lives so that we can become closer to Allah and receive His blessings.
