A river at your door

The five prayers wash away sins like bathing five times a day removes dirt.

Narrated by Abu Hurairah

Tell me, if there were a river at the door of one of you and he bathed in it five times every day, would any dirt remain on him? They said: "No dirt would remain on him." He said: "That is the likeness of the five prayers: through them Allah wipes out sins."

Sahih al-Bukhari 528, Sahih Muslim 667

What this hadith teaches

Every prayer is a fresh wash for the soul. The minor sins we fall into between prayers are cleaned away when we pray, as long as major sins are avoided.

أَرَأَيْتُمْ لَوْ أَنَّ نَهَرًا بِبَابِ أَحَدِكُمْ، يَغْتَسِلُ فِيهِ كُلَّ يَوْمٍ خَمْسًا، مَا تَقُولُ ذَلِكَ يُبْقِي مِنْ دَرَنِهِ ‏"‏‏.‏ قَالُوا لاَ يُبْقِي مِنْ دَرَنِهِ شَيْئًا‏.‏ قَالَ ‏"‏ فَذَلِكَ مِثْلُ الصَّلَوَاتِ الْخَمْسِ، يَمْحُو اللَّهُ بِهَا الْخَطَايَا
