It is narrated from Hazrat Hudhaifah bin Yaman (may Allah be pleased with him) that I saw the Noble Prophet (peace and blessings be upon him) come to a place where people threw their rubbish, and he stood and urinated there. Then he asked for water, which I brought to him. The Noble Prophet (peace and blessings be upon him) performed ablution and wiped over his leather socks.
