It is narrated from the Mother of the Believers Sayyidah Umm Salamah (may Allah be pleased with her) that "The Prophet (peace and blessings be upon him) would enter the morning in a state of major ritual impurity (janabah) because of intercourse, not because of a wet dream."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Rabi'ah bin Abi Abd al-Rahman (may Allah have mercy on him) except Sulayman bin Bilal (may Allah have mercy on him), and Ibn Abi Uways (may Allah have mercy on him) is alone in narrating it from his brother."
