It is narrated from Umm al-Mu'minin Sayyida Aisha (may Allah be pleased with her) and Sayyida Umm Salama (may Allah be pleased with her), both said that the Messenger of Allah (peace and blessings of Allah be upon him) would remain in a state of janabah due to intercourse, not due to a wet dream, and morning would come upon him in Ramadan, then he would fast.
