Perform wudu before praying .

This hadith is about the importance of performing ablution before prayer. It was narrated by Abdullah ibn Abbas, who said that the Prophet Muhammad came out from the privy and was presented with a question about whether they should bring him water for ablution. He replied that he had been commanded to perform ablution when he got up for prayer. This hadith teaches us that it is important to perform wudu before we pray, as this is a commandment from Allah and an act of worship which will be rewarded in the afterlife. It also shows us how much respect and reverence Muslims have towards their Prophet, as they were willing to bring him water even though it wasn't necessary.
