Wudu washes away sins

The Messenger of Allah ﷺ said: “When a Muslim —or a believer— performs wudu and (1) washes his face, every sin that his eyes have looked at comes out from his face with the water, or with the last drop of water. (2) When he washes his hands, every sin that his hands have committed comes out from his hands with the water, or with the last drop of water. (3) When he washes his feet, every sin that his feet have walked to comes out with the water, or with the last drop of water; until he emerges purified of sins.”

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ: «إِذَا تَوَضَّأَ الْعَبْدُ الْمُسْلِمُ أَوِ الْمُؤْمِنُ (١) فَغَسَلَ وَجْهَهُ خَرَجَ مِنْ وَجْهِهِ كُلُّ خَطِيئَةٍ نَظَرَ إِلَيْهَا بِعَيْنَيْهِ مَعَ الْمَاءِ أَوْ مَعَ آخِرِ قَطْرِ الْمَاءِ، (٢) فَإِذَا غَسَلَ يَدَيْهِ خَرَجَ مِنْ يَدَيْهِ كُلُّ خَطِيئَةٍ كَانَ بَطَشَتْهَا يَدَاهُ مَعَ الْمَاءِ أَوْ مَعَ آخِرِ قَطْرِ الْمَاءِ، (٣) فَإِذَا غَسَلَ رِجْلَيْهِ خَرَجَتْ كُلُّ خَطِيئَةٍ مَشَتْهَا رِجْلاَهُ مَعَ الْمَاءِ أَوْ مَعَ آخِرِ قَطْرِ الْمَاءِ، حَتَّى يَخْرُجَ نَقِيًّا مِنَ الذُّنُوبِ»

The Messenger of Allah (way peace be upon him) said: He who performed ablution well, his sins would come out from his body, even coming out from under his nails.

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ تَوَضَّأَ فَأَحْسَنَ الْوُضُوءَ خَرَجَتْ خَطَايَاهُ مِنْ جَسَدِهِ حَتَّى تَخْرُجَ مِنْ تَحْتِ أَظْفَارِهِ
