Sayyiduna Abu Samh (may Allah be pleased with him) narrates: I was the servant of the Prophet (peace and blessings be upon him). Sayyiduna Hasan or Sayyiduna Husayn (may Allah be pleased with them) was brought, and he urinated on the blessed chest of the Prophet (peace and blessings be upon him). The Companions (may Allah be pleased with them) wanted to wash it, but the Prophet (peace and blessings be upon him) said: "Sprinkle water over it, because the urine of a girl is washed, and the urine of a boy is sprinkled with water."
