It was narrated from Hudhaifah that: The Messenger of Allah came to the garbage dump of some people and he urinated on it standing up.

Shu'bah narrated from 'Asim from Abu Wa'il from Mughirah bin Shu'bah that: The Messenger of Allah came to the garbage dump of some people and urinated while standing up. (Hasan) Shu'bah said: "That day, 'Asim said: 'Amash reported this from Abu Wa'il, from Hudhaifah, but he did not remember it (correctly). So I asked Mansur about it, and he narrated it to me from Abu Wa'il, from Hudhaifah, that the Prophet came to a dump of some people and urinated while standing.'"
