Sunan Ibn Majah 283
It was narrated that 'Amr bin 'Abasah said:
"The Messenger of Allah said: 'When a person performs ablution and washes his hands, his sins exit through his hands. When he washes his face, his sins exit through his face. When he washes his forearms and wipes his head, his sins exit though his forearms and head. When he washes his feet, his sins exit through his feet.'"
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَمُحَمَّدُ بْنُ بَشَّارٍ، قَالاَ حَدَّثَنَا غُنْدَرٌ، مُحَمَّدُ بْنُ جَعْفَرٍ عَنْ شُعْبَةَ، عَنْ يَعْلَى بْنِ عَطَاءٍ، عَنْ يَزِيدَ بْنِ طَلْقٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الْبَيْلَمَانِيِّ، عَنْ عَمْرِو بْنِ عَبَسَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏
"‏ إِنَّ الْعَبْدَ إِذَا تَوَضَّأَ فَغَسَلَ يَدَيْهِ خَرَّتْ خَطَايَاهُ مِنْ يَدَيْهِ فَإِذَا غَسَلَ وَجْهَهُ خَرَّتْ خَطَايَاهُ مِنْ وَجْهِهِ فَإِذَا غَسَلَ ذِرَاعَيْهِ وَمَسَحَ بِرَأْسِهِ خَرَّتْ خَطَايَاهُ مِنْ ذِرَاعَيْهِ وَرَأْسِهِ فَإِذَا غَسَلَ رِجْلَيْهِ خَرَّتْ خَطَايَاهُ مِنْ رِجْلَيْهِ ‏"‏ ‏.‏
