“I heard the Messenger of Allah ﷺ say: ‘Do you think that if there was a river in the courtyard of anyone of you, and he bathed in it five times each day, would there be any dirt left on him?’ They said: ‘(There would be) nothing.’ He said: ‘Prayer takes away sins like water takes away dirt.’”  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ أَرَأَيْتَ لَوْ كَانَ بِفِنَاءِ أَحَدِكُمْ نَهْرٌ يَجْرِي يَغْتَسِلُ فِيهِ كُلَّ يَوْمٍ خَمْسَ مَرَّاتٍ مَا كَانَ يَبْقَى مِنْ دَرَنِهِ قَالَ لاَ شَىْءَ قَالَ فَإِنَّ الصَّلاَةَ تُذْهِبُ الذُّنُوبَ كَمَا يُذْهِبُ الْمَاءُ الدَّرَنَ  

‘Uthman said: I heard the Messenger of Allah ﷺ say: “Do you think if there was a river in the courtyard of one of you and he washed himself in it five times each day, would any dirt remain on him? They said: Nothing [would remain on him). He said: ʿThe (five daily) prayers take away sins as water takes away dirt.ʿ  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ أَرَأَيْتَ لَوْ كَانَ بِفِنَاءِ أَحَدِكُمْ نَهَرٌ يَجْرِي يَغْتَسِلُ مِنْهُ كُلَّ يَوْمٍ خَمْسَ مَرَّاتٍ مَا كَانَ يَبْقَى مِنْ دَرَنِهِ؟ قَالُوا لَا شَيْءَ قَالَ فَإِنَّ الصَّلَوَاتِ تُذْهِبُ الذُّنُوبَ كَمَا يُذْهِبُ الْمَاءُ الدَّرَنَ  

"عَنْ عُثْمَانَ: سَمِعْتُ رَسُولَ الله ﷺ يَقُولُ: أَرَأَيْتَ لَوْ أَنَّ بِفِنَاءِ أحَدِكُمْ نَهْرًا يَجْرِى يَغْتَسِلُ فِيهِ كُلَّ يَوْمٍ خَمْسَ مَرَّاتٍ، مَا كَانَ يَبْقَى مِنْ دَرَنِهِ؟ قَالُوا: لَا شَىْءَ، قَالَ: فَإِنَّ الصَّلَوَاتِ تُذْهِبُ الذُّنوبَ كَمَا يُذْهِبُ هَذَا الْمَاءُ الدَّرَنَ".
