The Prophet (ﷺ) said, "Say, if there were a river at the door of one of you in which he takes a bath fives times a day, would any soiling remain on him? They replied, "No soiling would left on him."
He (ﷺ) said, " That is the five (obligatory) Salat (prayers). Allah obliterates all sins as a result of performing them." [Al-Bukhari and Muslim, riyad as-salihin1042]
The Messager of Allah (ﷺ) said, "The similitude of the five (obligatory) Salat is like a river running at the door of one of you in which he takes a bath five times a day.' [Muslim,riyad as-salihin 1043].
