Islam is a religion of purity and cleanliness, and it guides the Muslim to that which will preserve his cleanliness. One of the most important means of achieving cleanliness is water, so Islam instructs us to protect it and not let it be contaminated with impurities, or to throw filthy things into it. In this hadith, the Prophet (blessings and peace of Allah be upon him) forbids urinating into standing water, which is stagnant water that does not flow and is not renewed, and then washing oneself with it. This prohibition is so that this action will not lead to the water becoming impure or being spoiled so that people find it off-putting. Moreover, such water is not fit to be used for washing oneself. In a report narrated by Muslim, there is an explanation of how to wash oneself with standing water. In that report it says: he should scoop the water out from it, meaning that he should take water from that pond or pool, then wash himself away from it. This also comes under the heading of protecting clean and pure water that is fit to be used, because the Muslim is enjoined to protect and preserve all kinds of water, whether flowing or stagnant. The emphasis is on being careful to preserve stagnant water because it is not renewed, and it is more likely to change or become spoiled if something is thrown into it, let alone if what is thrown into it is something impure (najis), such as urine and the like. .
