Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: What do you think, if there were a river at the door of one of you and he bathed in it five times a day, would any dirt remain on him? The people said: Nothing of his dirt would remain. The Prophet (peace and blessings be upon him) said: This is the example of the five prayers; Allah wipes away sins through them.
