Sayyidah Zaynab bint Jahsh (may Allah be pleased with her) narrates that the Prophet (peace and blessings be upon him) was sleeping at her place, and Sayyiduna Husayn (may Allah be pleased with him) was crawling around the house. She became heedless of him, and he crawled until he reached the Prophet (peace and blessings be upon him). Then the child climbed onto his (peace and blessings be upon him) stomach and placed his private part on his (peace and blessings be upon him) navel. She said: The Prophet (peace and blessings be upon him) woke up, and I got up and took him off his (peace and blessings be upon him) stomach, but the Prophet (peace and blessings be upon him) said: "Leave my son alone." When he had finished urinating, he (peace and blessings be upon him) took a jug of water and poured it over it, then said: "Water is poured over (the urine of) a boy, and (the urine of) a girl is washed." She said: Then he (peace and blessings be upon him) performed ablution (wudu) and stood up to pray, and he held him close; when he bowed and prostrated he would put him down, and when he stood up he would pick him up. Then when he sat, he began to supplicate, raising his hands in supplication. When he had completed the prayer, I said: O Messenger of Allah! Today I saw you (peace and blessings be upon him) do something I have never seen before. He (peace and blessings be upon him) said: "Jibril came to me and told me that this son of mine will be killed." I said: Then show me. And red soil was brought to me.
