5 – Abu Hurayrah — may Allah be pleased with him — reported that the Messenger of Allah ﷺ said: “None of you is to bathe in standing water when he is in a state of major ritual impurity.” Recorded by Muslim.
Al-Bukhari’s wording is: “None of you should urinate in stagnant water that does not flow, then bathe in it,” while Muslim adds: “from it.”
Abu Dawud reports: “Nor should he bathe in it to remove major ritual impurity.” (1)

Glossary of the ḥadith
• lā yaghtasil: lā of prohibition; it places the verb in the jussive, requesting the abandonment of the act. “Yaghtasil” is therefore jussive and ends with sukun.
• al-dāʾim: from dāma yadūmu (to remain), meaning water that stays in one place—still, motionless, stagnant.
• thumma yaghtasil: can be read in three ways: (i) jussive, coordinated with “lā yabūlanna”; (ii) accusative with an implied “an”; or (iii) indicative, understood as “then he is to bathe in it.”
• alladhī lā yajri: an explanation of “al-dāʾim,” referring to water that remains in one spot, such as pools in the wilderness.

• al-bawl (urine): physicians define it as a liquid the kidneys separate from the blood in order to expel it from the body. It carries excess water and salts, travels from the kidneys through the ureters to the bladder, where it accumulates until it leaves the body through
