Sahih Muslim , Hadith 226 ⓘ

Humran, the freed slave of 'Uthman, said: Uthman b. 'Affan called for ablution water and this is how he performed the ablution. He washed his hands thrice. He then rinsed his mouth and cleaned his nose with water (three times). He then washed his face three times, then washed his right arm up to the elbow three times, then washed his left arm like that, then wiped his head; then washed his right foot up to the ankle three times, then washed his left foot like that, and then said: I saw the Messenger of Allah perform ablution like this ablution of mine. Then the Messenger of Allah said: He who performs ablution like this ablution of mine and then stood up (for prayer) and offered two rak'ahs of prayer without allowing his thoughts to be distracted, all his previous sins are expiated. Ibn Shihab said: Our scholars remarked: This is the most complete of the ablutions performed for prayer.

حَدَّثَنِي أَبُو الطَّاهِرِ، أَحْمَدُ بْنُ عَمْرِو بْنِ عَبْدِ اللَّهِ بْنِ عَمْرِو بْنِ سَرْحٍ وَحَرْمَلَةُ بْنُ يَحْيَى التُّجِيبِيُّ قَالاَ أَخْبَرَنَا ابْنُ وَهْبٍ، عَنْ يُونُسَ، عَنِ ابْنِ شِهَابٍ، أَنَّ عَطَاءَ بْنَ يَزِيدَ اللَّيْثِيَّ، أَخْبَرَهُ أَنَّ حُمْرَانَ مَوْلَى عُثْمَانَ أَخْبَرَهُ أَنَّ عُثْمَانَ بْنَ عَفَّانَ - رضى الله عنه - دَعَا بِوَضُوءٍ فَتَوَضَّأَ فَغَسَلَ كَفَّيْهِ ثَلاَثَ مَرَّاتٍ ثُمَّ مَضْمَضَ وَاسْتَنْثَرَ ثُمَّ غَسَلَ وَجْهَهُ ثَلاَثَ مَرَّاتٍ ثُمَّ غَسَلَ يَدَهُ الْيُمْنَى إِلَى الْمِرْفَقِ ثَلاَثَ مَرَّاتٍ ثُمَّ غَسَلَ يَدَهُ الْيُسْرَى مِثْلَ ذَلِكَ ثُمَّ مَسَحَ رَأْسَهُ ثُمَّ غَسَلَ رِجْلَهُ الْيُمْنَى إِلَى الْكَعْبَيْنِ ثَلاَثَ مَرَّاتٍ ثُمَّ غَسَلَ الْيُسْرَى مِثْلَ ذَلِكَ ثُمَّ قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم تَوَضَّأَ نَحْوَ وُضُوئِي هَذَا ثُمَّ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ مَنْ تَوَضَّأَ نَحْوَ وُضُوئِي هَذَا ثُمَّ قَامَ فَرَكَعَ رَكْعَتَيْنِ لاَ يُحَدِّثُ فِيهِمَا نَفْسَهُ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ ‏" ‏ ‏.‏ قَالَ ابْنُ شِهَابٍ وَكَانَ عُلَمَاؤُنَا يَقُولُونَ هَذَا الْوُضُوءُ أَسْبَغُ مَا يَتَوَضَّأُ بِهِ أَحَدٌ لِلصَّلاَةِ ‏.‏

Humran, the freed slave of 'Uthman said: I saw Uthman call for a vessel (of water) and poured water over his hands three times and then washed them. Then he put his right hand in the vessel and rinsed his mouth and cleaned his nose. Then he washed his face three times and his hands up to the elbow three times; then wiped his head, then washed his feet three times. Then he said that the Messenger of Allah had said: He who performed ablution like this ablution of mine and offered two raklahs of prayer without allowing his thoughts to be distracted, all his previous sins would be expiated.

وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا أَبِي، عَنِ ابْنِ شِهَابٍ، عَنْ عَطَاءِ بْنِ يَزِيدَ اللَّيْثِيِّ، عَنْ حُمْرَانَ، مَوْلَى عُثْمَانَ أَنَّهُ رَأَى عُثْمَانَ دَعَا بِإِنَاءٍ فَأَفْرَغَ عَلَى كَفَّيْهِ ثَلاَثَ مِرَارٍ فَغَسَلَهُمَا ثُمَّ أَدْخَلَ يَمِينَهُ فِي الإِنَاءِ فَمَضْمَضَ وَاسْتَنْثَرَ ثُمَّ غَسَلَ وَجْهَهُ ثَلاَثَ مَرَّاتٍ وَيَدَيْهِ إِلَى الْمِرْفَقَيْنِ ثَلاَثَ مَرَّاتٍ ثُمَّ مَسَحَ بِرَأْسِهِ ثُمَّ غَسَلَ رِجْلَيْهِ ثَلاَثَ مَرَّاتٍ ثُمَّ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ مَنْ تَوَضَّأَ نَحْوَ وُضُوئِي هَذَا ثُمَّ صَلَّى رَكْعَتَيْنِ لاَ يُحَدِّثُ فِيهِمَا نَفْسَهُ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ ‏" ‏ ‏.‏
