Sayyidah Lubabah bint al-Harith (may Allah be pleased with her) said: Hasan bin Ali urinated in the lap of the Prophet (peace and blessings be upon him), so I said: "Give me your garment and put on another garment." He (peace and blessings be upon him) said: "The garment is washed of the urine of a female (child), and water is sprinkled over the urine of a male (child)."
