How to Perform Ablution - Section 3
وَعَنْ عُثْمَانَ رَضِيَ اللَّهُ عَنْهُ قَالَ: إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ تَوَضَّأَ ثَلَاثًا ثَلَاثًا وَقَالَ: «هَذَا وُضُوئِي وَوُضُوءُ الْأَنْبِيَاءِ قَبْلِي وَوُضُوءُ إِبْرَاهِيمَ» . رَوَاهُمَا رَزِينٌ وَالنَّوَوِيُّ ضَعَّفَ الثَّانِي فِي شرح مُسلم
‘Uthman said that God’s messenger performed each detail of ablution three times and then said, “This is how I perform ablution, how the prophets before me performed it, and how Abraham performed it.” Razin transmitted these two traditions, but in his commentary on Muslim Nawawi declared the second to be weak.
