Abu Bakr (RA) reported that Marwan sent him to Umm Salamah to ask whether a person should observe fast who is in a state of junub and the dawn breaks upon him, whereupon she said that the Messenger of Allah ﷺ (was at times) junbi on account of intercourse and not due to sexual dream, and the dawn broke upon him, but he neither broke the fast nor recompensed.
