Hadhrat Abu Hurairah (Radhiyallaho anho) narrates that once the Prophet (Sallallaho alaihe wasallam) asked his companions, ‘Do you believe that dirt can remain on a person bathing five times a day in a brook 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 offered five times a day. With the Grace of Allah. it washes away all the sins’.” (Bukhari, Muslim, Tirmidzi, Nasa’i, Ibn Majah)
Hadhrat Jaabir (Radhiyallaho anho) narrates that he heard the Prophet (Sallallaho alaihe wasallam) saying: “The likeness of five times daily salaat is as the likeness of a deep brook running in front of the door of a person who bathes therein five times a day.” (Muslim)
إِلَّا الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ فَلَهُمْ أَجْرٌ غَيْرُ مَمْنُونٍ
