وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ سُهَيْلِ بْنِ أَبِي صَالِحٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ إِذَا تَوَضَّأَ الْعَبْدُ الْمُسْلِمُ - أَوِ الْمُؤْمِنُ - فَغَسَلَ وَجْهَهُ خَرَجَتْ مِنْ وَجْهِهِ كُلُّ خَطِيئَةٍ نَظَرَ إِلَيْهَا بِعَيْنَيْهِ مَعَ الْمَاءِ - أَوْ مَعَ آخِرِ قَطْرِ الْمَاءِ - فَإِذَا غَسَلَ يَدَيْهِ خَرَجَتْ مِنْ يَدَيْهِ كُلُّ خَطِيئَةٍ بَطَشَتْهَا يَدَاهُ مَعَ الْمَاءِ - أَوْ مَعَ آخِرِ قَطْرِ الْمَاءِ فَإِذَا غَسَلَ رِجْلَيْهِ خَرَجَتْ كُلُّ خَطِيئَةٍ مَشَتْهَا رِجْلاَهُ مَعَ الْمَاءِ - أَوْ مَعَ آخِرِ قَطْرِ الْمَاءِ - حَتَّى يَخْرُجَ نَقِيًّا مِنَ الذُّنُوبِ ‏"‏ ‏.‏

Yahya related to me from Malik from Suhayl ibn Abi Salih from hisfather from Abu Hurayra that the Messenger of Allah, may Allah blesshim and grant him peace, said, "A muslim slave (or a trusting slave)does wudu and as he washes his face every wrong action he has seenwith his eyes leaves with the water (or the last drop of water). As hewashes his hands every wrong action he has done with his hands leaveswith the water (orthe last drop of water). And as he washes his feetevery wrong action his feet have walked to leaves with the water (orthe last drop of water) so that he comes away purified of wrongactions." Translation Not Available
