Hadith: What if there was a river at the door of any of you wherein he takes a bath five times a day? Would there remain any of his filth?

عَنْ أَبِي هُرَيْرَةَ رضي الله عنه أَنَّهُ سَمِعَ رَسُولَ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَقُولُ:
«أَرَأَيْتُمْ لَوْ أَنَّ نَهَرًا بِبَابِ أَحَدِكُمْ يَغْتَسِلُ فِيهِ كُلَّ يَوْمٍ خَمْسًا، مَا تَقُولُ ذَلِكَ يُبْقِي مِنْ دَرَنِهِ؟» قَالُوا: لَا يُبْقِي مِنْ دَرَنِهِ شَيْئًا، قَالَ: «فَذَلِكَ مِثْلُ الصَّلَوَاتِ الخَمْسِ، يَمْحُو اللَّهُ بِهِ الخَطَايَا».
[صحيح] - [متفق عليه] - [صحيح البخاري: 528]

Abu Hurayrah (may Allah be pleased with him) reported that he heard the Messenger of Allah (may Allah's peace and blessings be upon him) say:
"What if there was a river at the door of any of you wherein he takes a bath five times a day? Would there remain any of his filth?" They said: Nothing of his filth would remain. He said: "This is similar to the five prayers by means of which Allah erases sins."
[Authentic hadith] - [Narrated by Bukhari & Muslim] - [Sahih Bukhari - 528]

Explanation

The Prophet (may Allah's peace and blessings be upon him) likened the five prayers every day and night and their effect on removing and expiating minor sins and misdeeds to a river at one's door wherefrom he takes a bath five times every day and, thus, nothing of his dirt or filth remains.
