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 ﷺ perform ablution like this ablution of mine. Then the Messenger of Allah ﷺ 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.  

أَنَّ عُثْمَانَ بْنَ عَفَّانَ ؓ دَعَا بِوَضُوءٍ فَتَوَضَّأَ: (١) فَغَسَلَ كَفَّيْهِ ثَلاَثَ مَرَّاتٍ، ثُمَّ (٢) مَضْمَضَ، (٣) وَاسْتَنْثَرَ، ثُمَّ (٤) غَسَلَ وَجْهَهُ ثَلاَثَ مَرَّاتٍ، ثُمَّ (٥) غَسَلَ يَدَهُ الْيُمْنَى إِلَى الْمِرْفَقِ ثَلاَثَ مَرَّاتٍ، (٦) ثُمَّ غَسَلَ يَدَهُ الْيُسْرَى مِثْلَ ذَلِكَ، ثُمَّ (٧) مَسَحَ رَأْسَهُ، ثُمَّ (٨) غَسَلَ رِجْلَهُ الْيُمْنَى إِلَى الْكَعْبَيْنِ ثَلاَثَ مَرَّاتٍ، ثُمَّ (٩) غَسَلَ الْيُسْرَى مِثْلَ ذَلِكَ، ثُمَّ قَالَ: رَأَيْتُ رَسُولَ اللَّهِ ﷺ تَوَضَّأَ نَحْوَ وُضُوئِي هَذَا، ثُمَّ قَالَ رَسُولُ اللَّهِ ﷺ: «مَنْ تَوَضَّأَ نَحْوَ وُضُوئِي هَذَا ثُمَّ قَامَ فَرَكَعَ رَكْعَتَيْنِ لاَ يُحَدِّثُ فِيهِمَا نَفْسَهُ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ۔»  

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 ﷺ had said: He who performed ablution like this ablution of mine and offered two rakaʿahs of prayer without allowing his thoughts to be distracted, all his previous sins would be expiated.  

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 ﷺ مَنْ تَوَضَّأَ نَحْوَ وُضُوئِي هَذَا ثُمَّ صَلَّى رَكْعَتَيْنِ لاَ يُحَدِّثُ فِيهِمَا نَفْسَهُ غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ
