عَنْ أَبِي هُرَيْرَةَ رَضيَ اللهُ عنهُ أَنَّ رَسُولَ اللهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ: «إِذَا تَوَضَّأَ الْعَبْدُ الْمُسْلِمُ -أَوِ الْمُؤْمِنُ- فَغَسَلَ وَجْهَهُ خَرَجَ مِنْ وَجْهِهِ كُلُّ خَطِيئَةٍ نَظَرَ إِلَيْهَا بِعَيْنَيْهِ مَعَ الْمَاءِ -أَوْ مَعَ آخِرِ قَطْرِ الْمَاءِ-، فَإِذَا غَسَلَ يَدَيْهِ خَرَجَ مِنْ يَدَيْهِ كُلُّ خَطِيئَةٍ كَانَ بَطَشَتْهَا يَدَاهُ مَعَ الْمَاءِ -أَوْ مَعَ آخِرِ قَطْرِ الْمَاءِ-، فَإِذَا غَسَلَ رِجْلَيْهِ خَرَجَتْ كُلُّ خَطِيئَةٍ مَشَتْهَا رِجْلَاهُ مَعَ الْمَاءِ -أَوْ مَعَ آخِرِ قَطْرِ الْمَاءِ- حَتَّى يَخْرُجَ نَقِيًّا مِنَ الذُّنُوبِ».
Kutoka kwa Abuu Huraira radhi za Allah ziwe juu yake yakwamba Mtume rehema na amani ziwe juu yake amesema: "Pindi mja muislamu au muumini atakapotawadha akaosha uso wake, madhambi yake yote yanayotokana na kuangalia yanaondoka na tone la maji au tone la mwisho usoni mwake, akiosha mikono yake yanaondoka madhambi yote yatokanayo na mikono pamoja na tone la mwisho, akiosha miguu yake madhambi yote yatokanayo na kutembea yanaondoka na tone la mwisho, mpaka muislamu anabaki msafi hana madhambi".
Abu Hurayrah (may Allah be pleased with him) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "When a Muslim—or a believer—performs ablution, and he washes his face, every sin he has looked at with his eyes comes out of his face with the water or with the last drop of water. When he washes his hands, every sin he has struck with his hands comes out of his hands with the water or with the last drop of water. When he washes his feet, every sin his feet walked towards comes out with the water or with the last drop of water—until he comes out cleansed of sins."
Fadhila za kuhifadhi udhu, nakuwa unafuta madhambi.
Miongoni mwa muongozo wa Mtume rehema na amani ziwe juu yake ni kuwahimiza watu katika utiifu na ibada, na kutaja malipo na thawabu zake.
Kila kiungo miogoni mwa viungo vya mwanadamu huingia katika baadhi ya madhambi, na ndio maana madhambi hukifuata kila kiungo kilichoyafanya, na hutoka na kila kiungo kilichotubia kwayo.
Udhu una usafi wa wazi, na unakuwa pale vinapooshwa viungo vya udhu, na usafi usioonekana; na unakuwa kutokana na madhambi yaliyotokea kupitia viungo.
