It is narrated from Umm al-Mu'mineen 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 in a state where ghusl (ritual bath) is obligatory upon me, and I also want to fast, what should I do?" The Prophet (peace and blessings be upon him) replied, "If such a situation occurs with me, I perform ghusl and then keep the fast." The man said, "We are not like you; Allah Almighty has forgiven all your past and future sins." At 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."
