Muwatta Malik, Book 2, Hadith 31 (USC-MSA) ⓘ

Yahya related to me from Malik from Zayd ibn Aslam from Ata ibn Yasar from Abdullah as-Sanabihi that the Messenger of Allah, may Allah bless him and grant him peace, said, "A trusting slave does wudu and as he rinses his mouth the wrong actions leave it. As he cleans his nose the wrong actions leave it. As he washes his face, the wrong actions leave it, even from underneath his eyelashes. As he washes his hands the wrong actions leave them, even from underneath his fingernails. As he wipes his head the wrong actions leave it, even from his ears. And as he washes his feet the wrong actions leave them, even from underneath the toenails of both his feet." He added, "Then his walking to the mosque and his prayer are an extra reward for him."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ عَبْدِ اللَّهِ الصُّنَابِحِيِّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ إِذَا تَوَضَّأَ الْعَبْدُ الْمُؤْمِنُ فَتَمَضْمَضَ خَرَجَتِ الْخَطَايَا مِنْ فِيهِ وَإِذَا اسْتَنْثَرَ خَرَجَتِ الْخَطَايَا مِنْ أَنْفِهِ فَإِذَا غَسَلَ وَجْهَهُ خَرَجَتِ الْخَطَايَا مِنْ وَجْهِهِ حَتَّى تَخْرُجَ مِنْ تَحْتِ أَشْفَارِ عَيْنَيْهِ فَإِذَا غَسَلَ يَدَيْهِ خَرَجَتِ الْخَطَايَا مِنْ يَدَيْهِ حَتَّى تَخْرُجَ مِنْ تَحْتِ أَظْفَارِ يَدَيْهِ فَإِذَا مَسَحَ بِرَأْسِهِ خَرَجَتِ الْخَطَايَا مِنْ رَأْسِهِ حَتَّى تَخْرُجَ مِنْ أُذُنَيْهِ فَإِذَا غَسَلَ رِجْلَيْهِ خَرَجَتِ الْخَطَايَا مِنْ رِجْلَيْهِ حَتَّى تَخْرُجَ مِنْ تَحْتِ أَظْفَارِ رِجْلَيْهِ - قَالَ - ثُمَّ كَانَ مَشْيُهُ إِلَى الْمَسْجِدِ وَصَلاَتُهُ نَافِلَةً لَهُ ‏" ‏ ‏.‏
