The Prophet (blessings and peace of Allah be upon him) was the best teacher and the most eloquent of the people in speech. One of the effective ways in which he educated and taught people was by making knowledge straightforward and easy to understand, by giving tangible likenesses to make things clearer. In this hadith, the Prophet (blessings and peace of Allah be upon him) gives the likeness of how sins are erased by means of the five daily prayers, as he likened the five daily prayers to a river at the door of a person in which he bathes five times every day. Just as all dirt would be removed from him, so that there would be no trace of dirt left on him, in like manner the five daily prayers erase sins and misdeeds until there is nothing left of them. The reason for that is that just as a person may become contaminated with physical dirt on his body and clothes, which he cleanses by means of abundant water, by the same token, the prayers cleanse a person of the dirt of sin, until there is no sin left that has not been expiated and removed, so long as he avoids major sins, as it was narrated in a sahih report by Muslim that the Prophet (blessings and peace of Allah be upon him) said: “The five daily prayers, one Jumu‘ah to the next, and one Ramadan to the next, are expiation for what comes between them, so long as major sins are avoided.” The view of many scholars is that the prayers expiate all minor sins, so long as one does not persist in them, because by persisting in them they become major sins. As for major sins, they require complete repentance, fulfilling all the necessary conditions..
