Musannaf Ibn Abi Shaybah 38879 — Banishing the male and female

Sayyidah Lubabah bint al-Harith (may Allah be pleased with her) reports that al-Husayn bin Ali (may Allah be pleased with him) urinated on the Prophet (peace and blessings be upon him). So I said: "Give me these clothes (so that I may wash them) and put on something else." He said: "Water is sprinkled over the urine of a boy, and the urine of a girl is washed."
