It was narrated from Abu Hurairah that the Messenger of Allah (ﷺ) forbade urinating into standing water then performing Ghusl with it.
Sunan an-Nasa'i Book 4, Hadith 4
← Previous Hadith It was narrated from Abu Hurairah that the Messenger of Allah (ﷺ) forbade urinating into standing water and then performing Ghusl from Janabah in it.

Sunan an-Nasa'i Book 4, Hadith 3 Next Hadith → "None of you should urinate into standing water which does not flow and then perform Ghusl with it." (One of the narrators) Sufyan said: "They said to Hisham - meaning Ibn Hassan - 'Ayyub only attributed this Hadith to Abu Hurairah?' So he said: 'If Ayyub is not able to raise up a narration then he does not raise it.'"

That is, he narrated it from Abu Hurairah, rather than from him from the Prophet (ﷺ) while others narrated it in Marfu' form or "raised" to the Prophet (ﷺ) And perhaps by: "If he is able to not raise it" he means: "If he is not able to raise it." And Allah knows best.
