MUSLIM 1109c:
from al-a man Yuṣbiḥ Junub Ayaṣūm —
Abu Bakr reported that Marwan sent him to Umm Salama 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.
مسلم ١١٠٩c:
عن الا من يصبح جنب ايصوم —
أَنَّ مَرْوَانَ أَرْسَلَهُ إِلَى أُمِّ سَلَمَةَ ؓ يَسْأَلُ عَنِ الرَّجُلِ يُصْبِحُ جُنُبًا أَيَصُومُ فَقَالَتْ كَانَ رَسُولُ اللَّهِ ﷺ يُصْبِحُ جُنُبًا مِنْ جِمَاعٍ لاَ مِنْ حُلُمٍ ثُمَّ لاَ يُفْطِرُ وَلاَ يَقْضِي
