Be mindful when performing wudu; Ensure sources of still waters are kept clean; Strive for physical and spiritual cleanliness in life.

This hadith is about the importance of cleanliness and purity in Islam. It was narrated by Abu Hurairah that the Messenger of Allah said, "None of you should urinate into still water and then perform Wudu' with it". This hadith teaches us that we must be mindful of our actions and take care to ensure that we are not contaminating any source of water, as this would make it impure and unsuitable for performing wudu. We must also be aware that if we do contaminate a source of water, then it cannot be used for wudu or other religious purposes until it has been purified again. The Prophet's words remind us to always strive for cleanliness in our lives, both physically and spiritually.
