Hadith: Salaah

Once The Messenger of Allah (S.W.T.), Muhammad [Peace be upon him] asked his companions, 'Do you believe that dirt can remain on a person bathing five times a day in a stream [river] running in front of his door?' 'No', replied the companions, 'No dirt can remain on his body.' The Prophet (Sallallaho alaihe wasallam) remarked: So, exactly similar is the effect of salaat[prayer] offered five times a day. With the Grace of Allah, it washes away all the sins'." ( Hadith)
