Abu Bakr bin Abdur Rahman says that Hazrat Abu Hurairah (may Allah be pleased with him) used to say that the fast of a person who is in a state of major ritual impurity (janabah) in the morning is not valid. I mentioned this to Hazrat Aisha (may Allah be pleased with her), and she said, "There is no basis for his statement. Sometimes the Prophet (peace and blessings be upon him) would be in a state of janabah in the morning, then he would perform ghusl and complete the rest of the day's fast. Then Bilal would come and inform him of the prayer, and he would go out and lead the people in prayer while water would be dripping from his body."
