"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 اللهِ ﷺ يَقُولُ أَرَأَيْتُمْ لَوْ أَنَّ نَهْرًا بِبَابِ أَحَدِكُمْ يَغْتَسِلُ مِنْهُ كُلَّ يَوْمٍ خَمْسَ مَرَّاتٍ مَا تَقُولُونَ؟ هَلْ يَبْقَى مِنْ دَرَنِهِ؟ قَالُوا لَا يَبْقَى مِنْ دَرَنِهِ شَيْءٌ قَالَ ذَاكَ مَثَلُ الصَّلَوَاتِ الْخَمْسِ يَمْحُو اللهُ بِهَا الْخَطَايَا
