[Machine] The Messenger of Allah ﷺ said, "The example of the prescribed prayers is like a river flowing fresh at the door of one of you, from which he washes five times a day."  

قَالَ رَسُولُ اللَّهِ ﷺ «مَثَلُ الصَّلَوَاتِ الْمَكْتُوبَاتِ كَمَثَلِ نَهَرٍ جَارٍ عَذْبٍ عَلَى بَابِ أَحَدِكُمْ يَغْتَسِلُ مِنْهُ كُلَّ يَوْمٍ خَمْسَ مَرَّاتٍ»  

"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." (Using translation from Nasāʾī 462)   

أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ «أَرَأَيْتُمْ لَوْ أَنَّ نَهَرًا بِبَابِ أَحَدِكُمْ يَغْتَسِلُ كُلَّ يَوْمٍ خَمْسَ مَرَّاتٍ مَاذَا تَقُولُونَ ذَلِكَ مُبْقِيًا مِنْ دَرَنِهِ؟» قَالُوا لَا يُبْقِي مِنْ دَرَنِهِ قَالَ «كَذَلِكَ مَثَلُ الصَّلَوَاتِ الْخَمْسِ يَمْحُو اللَّهُ بِهِنَّ الْخَطَايَا»
