Narrated Abu Wail: Abu Musa Al-Ash`ari used to lay great stress on the question of urination and he used to say, "If anyone from Bani Israel happened to soil his clothes with urine, he used to cut that portion away." Hearing that, Hudhaifa said to Abu Wail, "I wish he (Abu Musa) didn't (lay great stress on that matter)." Hudhaifa added, "Allah's Apostle went to the dumps of some people and urinated while standing."

Narrated Hudhaifa: Once the Prophet went to the dumps of some people and passed urine while standing. He then asked for water and so I brought it to him and he performed ablution.

Narrated Hudhaifa': The Prophet and I walked till we reached the dumps of some people. He stood, as any one of you stands, behind a wall and urinated. I went away, but he beckoned me to come. So I approached him and stood near his back till he finished.

Narrated Hudhaifa: I saw Allah's Apostle coming (or the Prophet came) to the dumps of some people and urinated there while standing .
