I saw ʿUthman bin ʿAffan ؓ do wudooʿ, He poured water onto his hands three times and washed them, then he rinsed his mouth and nose, then he washed his face three times, then he washed his right arm up to the elbow three times, then the left arm likewise, then he wiped his head, then he washed his right foot three times, then the left foot likewise. He said: I saw the Messenger of Allah ﷺ do wudooʿ similar to what I just did, then he said: “Whoever does wudooʿ as I just did, then prays two rak’ahs without letting his mind wander, his previous sins will be forgiven” (Using translation from Aḥmad 421)

أَنَّ عُثْمَانَ بْنَ عَفَّانَ رِضْوَانُ اللَّهِ عَلَيْهِ دَعَا بِوَضُوءٍ فَتَوَضَّأَ وَغَسَلَ كَفَّهُ ثَلَاثَ مَرَّاتٍ ثُمَّ مَضْمَضَ وَاسْتَنْشَقَ ثُمَّ غَسَلَ وَجْهَهَ 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 ﷺ تَوَضَّأَ نَحْوَ وُضُوئِي هَذَا ثُمَّ قَالَ رَسُولُ اللَّهِ ﷺ « تَوَضَّأَ نَحْوَ وُضُوئِي هَذَا ثُمَّ قَامَ فَرَكَعَ رَكْعَتَيْنِ لَا يُحَدِّثُ فِيهِمَا نَفْسَهُ غَفَرَ اللَّهُ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ»
