Abdur Rahman bin Atab says that Hazrat Abu Hurairah (may Allah be pleased with him) used to say that if a person is in a state of major ritual impurity (junub) in the morning, his fast is not valid. Once, Marwan bin Hakam sent me along with another man to Hazrat Aisha (may Allah be pleased with her) and Hazrat Umm Salamah (may Allah be pleased with her) to ask: If a person enters the morning in the month of Ramadan in a state of major ritual impurity and has not yet performed ghusl (ritual bath), what is the ruling? One of them said that sometimes the Prophet (peace and blessings be upon him) would enter the morning in a state of major ritual impurity, not due to a wet dream but by choice, and he would complete his fast. Both of us returned and informed Marwan of this. Marwan said to me, "Go and tell this to Hazrat Abu Hurairah (may Allah be pleased with him)." Hazrat Abu Hurairah (may Allah be pleased with him) said, "That was my opinion, or that is what I thought." Marwan said, "Are you giving people fatwas based on your opinion and assumption?"
