Sayyiduna Ismah (may Allah be pleased with him) narrates: Once, in one of the streets of Madinah, the Prophet (peace and blessings be upon him) came out to us. He reached a rubbish heap belonging to some people and said: "O Hudhayfah! Screen me!" Then the Prophet (peace and blessings be upon him) stood and urinated standing. Then he called for water, performed ablution, wiped over the leather socks and offered the prayer.
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator, al-Fadl bin al-Mukhtar, and he is munkar al-hadith (his hadith are rejected); he narrates false reports.
