(The third chain) It is narrated from Sayyida Umm Fadl (may Allah be pleased with her) that she used to breastfeed Sayyiduna Hasan (may Allah be pleased with him) or Sayyiduna Husayn (may Allah be pleased with him). She says: The Messenger of Allah (peace and blessings be upon him) came and sat down in a place that had been sprinkled with water, and placed him on his stomach, and he urinated on the stomach of the Prophet (peace and blessings be upon him). So I saw that the urine was flowing on the stomach of the Prophet (peace and blessings be upon him). I went towards a water-skin so that I could pour its water over the Prophet (peace and blessings be upon him), but the Prophet (peace and blessings be upon him) said: "O Umm Fadl! The urine of a boy is washed away with water, and the urine of a girl is washed thoroughly."
