Sunan Ibn Majah Book 1, Hadith 282

حَدَّثَنَا سُوَيْدُ بْنُ سَعِيدٍ، حَدَّثَنِي حَفْصُ بْنُ مَيْسَرَةَ، حَدَّثَنِي زَيْدُ بْنُ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنْ عَبْدِ اللَّهِ الصُّنَابِحِيِّ، عَنْ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ قَالَ ‏ "‏ مَنْ تَوَضَّأَ فَمَضْمَضَ وَاسْتَنْشَقَ خَرَجَتْ خَطَايَاهُ مِنْ فَمِهِ وَأَنْفِهِ فَإِذَا غَسَلَ وَجْهَهُ خَرَجَتْ خَطَايَاهُ مِنْ وَجْهِهِ حَتَّى تَخْرُجَ مِنْ تَحْتِ أَشْفَارِ عَيْنَيْهِ فَإِذَا غَسَلَ يَدَيْهِ خَرَجَتْ خَطَايَاهُ مِنْ يَدَيْهِ فَإِذَا مَسَحَ رَأْسَهُ خَرَجَتْ خَطَايَاهُ مِنْ رَأْسِهِ حَتَّى تَخْرُجَ مِنْ أُذُنَيْهِ فَإِذَا غَسَلَ رِجْلَيْهِ خَرَجَتْ خَطَايَاهُ مِنْ رِجْلَيْهِ حَتَّى تَخْرُجَ مِنْ تَحْتِ أَظْفَارِ رِجْلَيْهِ وَكَانَتْ صَلاَتُهُ وَمَشْيُهُ إِلَى الْمَسْجِدِ نَافِلَةً ‏"‏ ‏.‏

It was narrated from 'Abdullah As-Sunabihi that:The Messenger of Allah said: "Whoever performs ablution and rinses his mouth and nose, his sins will exit through his mouth and nose. When he washes his face, his sins will exit from his face, even from beneath his eyelids. When he washes his hands, his sins will exit from his hands. When he wipes his head, his sins will exit from his head, and even from his ears. When he washes his feet, his sins will exit from his feet, even from beneath his toenails. Then his prayer and walking towards the mosque will earn extra merit for him
