Harun ibn Sa‘id al-Ayli narrated to me: Ibn Wahb narrated to us: ‘Amr — that is, Ibn al-Harith — informed me, from ‘Abd Rabbihi, from ‘Abdullah ibn Ka‘b al-Himyari, that Abu Bakr narrated to him that Marwan sent him to Umm Salamah — may Allah be pleased with her — to ask about a man who wakes up in a state of major ritual impurity (junub): should he fast? She said: "The Messenger of Allah ﷺ would wake up in a state of major ritual impurity from intercourse, not from a wet dream, and then he would not break his fast and would not make it up."
