It is narrated from Hazrat Aisha (may Allah be pleased with her) that a man asked the Prophet (peace and blessings be upon him), "O Messenger of Allah! If the time for prayer comes, I am required to perform ghusl, and I also want to fast, what should I do?" The Prophet (peace and blessings be upon him) said, "If such a situation were to happen to me, I would perform ghusl and then fast." The man said, "We are not like you; Allah Almighty has forgiven all your past and future sins." Upon this, the Prophet (peace and blessings be upon him) became displeased, and signs of anger appeared on his blessed face, and he said, "By Allah, I hope that I am the most God-fearing among you and the most knowledgeable about Him."
