أَخْبَرَنَا أَحْمَدُ بْنُ عَمْرِو بْنِ السَّرْحِ، ‏‏‏‏‏‏وَالْحَارِثُ بْنُ مِسْكِينٍ قِرَاءَةً عَلَيْهِ وَأَنَا أَسْمَعُ وَاللَّفْظُ لَهُ، ‏‏‏‏‏‏عَنْ ابْنِ وَهْبٍ، ‏‏‏‏‏‏عَنْيُونُسَ، ‏‏‏‏‏‏عَنْ ابْنِ شِهَابٍ، ‏‏‏‏‏‏أَنَّ عَطَاءَ بْنَ يَزِيدَ اللَّيْثِيَّ أَخْبَرَهُ، ‏‏‏‏‏‏أَنَّ حُمْرَانَ مَوْلَى عُثْمَانَ أَخْبَرَهُ، ‏‏‏‏‏‏أَنَّ عُثْمَانَ دَعَا بِوَضُوءٍ فَتَوَضَّأَ فَغَسَلَ كَفَّيْهِ ثَلَاثَ مَرَّاتٍ، ‏‏‏‏‏‏ثُمَّ مَضْمَضَ وَاسْتَنْشَقَ، ‏‏‏‏‏‏ثُمَّ غَسَلَ وَجْهَهُ ثَلَاثَ مَرَّاتٍ، ‏‏‏‏‏‏ثُمَّ غَسَلَ يَدَهُ الْيُمْنَى إِلَى الْمِرْفَقِ ثَلَاثَ مَرَّاتٍ، ‏‏‏‏‏‏ثُمَّ غَسَلَ يَدَهُ الْيُسْرَى مِثْلَ ذَلِكَ، ‏‏‏‏‏‏ثُمَّ مَسَحَ بِرَأْسِهِ، ‏‏‏‏‏‏ثُمَّ غَسَلَ رِجْلَهُ الْيُمْنَى إِلَى الْكَعْبَيْنِ ثَلَاثَ مَرَّاتٍ، ‏‏‏‏‏‏ثُمَّ غَسَلَ رِجْلَهُ الْيُسْرَى مِثْلَ ذَلِكَ، ‏‏‏‏‏‏ثُمَّ قَالَ:‏‏‏‏ رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ تَوَضَّأَ نَحْوَ وُضُوئِي هَذَا. ثُمَّ قَالَ:‏‏‏‏ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ:‏‏‏‏ مَنْ تَوَضَّأَ نَحْوَ وُضُوئِي هَذَا ثُمَّ قَامَ فَرَكَعَ رَكْعَتَيْنِ لَا يُحَدِّثُ فِيهِمَا نَفْسَهُ، ‏‏‏‏‏‏غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ .

It was narrated that Humran the freed slave of 'Uthman said: Uthman called for water for Wudu'. He washed his hands three times, then he rinsed his mouth and nose, then he washed his face three times, then washed his right hand up to the elbow three times. Then he washed his left hand likewise. Then he washed his left hand likewise. Then he wiped his head, then he washed his right foot up to the ankle three times, and he washed his left foot likewise, and he washed his left foot likewise. Then he said: 'I saw the Messenger of Allah (ﷺ) performing Wudu' as I have just done.' Then he said: The Messenger of Allah (ﷺ) said: 'Whoever performs Wudu' as I have just done, then prayes two Rak'ahs without letting his thoughts wander, his previous sins will be forgiven.'
