Abu Bakr (RA) bin 'Abdul Rahman bin al-Harith bin Hisham reported on the authority of 'A'isha and Umm Salamah, the wives of the Apostle of Allah (ﷺ) : The Messenger of Allah (ﷺ) at times got up in the morning in a state of junub on account of having a sexual intercourse (with his wives during night) but not due to sexual dreams in the month of Ramadan, and would observe fast.
