In the hadith narrated of the authority of Abd Huraira the Messenger of Allah (ﷺ) is reported to have said. while in the hadith narrated by Bakr (the words are like this): He heard the Messenger of Allah (ﷺ) as saying: just see, can anything of his filthiness remain (on the body of) any one of you if there were a river at his door in which he washed himself five times daily? They, said: Nothing of his filthiness will remain (on his body). He said: That is like the five prayers by which Allah obliterates sins. (Sahih Muslim 667)
It was narrated from Abu Hurairah that the Messenger of Allah (ﷺ) said: "Do you think that is there was a river by the door of any one of you, and he bathed in it five times each day, would there be any trace of dirt left on him?" They said: "No trace of dirt would be left on him." He said: "That is the likeness of the five daily prayers. By means of them Allah erases sins." (Sunan an-Nasa'i 462)
