Perform ablutions before prayer according to Prophet Muhammad's example.

This hadith is about how to perform wudoo, which is a ritual washing performed by Muslims before prayer. It was narrated from 'Ali ibn Abi Talib that he washed his hands three times, rinsed his mouth and nose three times, washed his face three times and said that this was the wudoo of the Messenger of Allah. This hadith teaches us that we should follow in the footsteps of Prophet Muhammad by performing our ablutions in this manner before prayer. It also teaches us to be mindful and take care when performing our religious duties as it can help us to become closer to God.
