Sayyiduna Hudhayfah (may Allah be pleased with him) narrates that (once) I and the Messenger of Allah (peace and blessings be upon him) were walking when we reached a garbage dump of a people (which) was behind a wall. The Prophet stood in such a way as any one of you would stand, then he urinated. I moved aside, but he signaled to me, so I stood near his heels (for the purpose of providing cover) until he finished urinating.
