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.'"
