وَعَنْ عُثْمَانَ رَضِيَ اللَّهُ عَنْهُ أَنَّهُ تَوَضَّأَ بِالْمَقَاعِدِ فَقَالَ: أَلَا أُرِيكُمْ وُضُوءَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ؟ فَتَوَضَّأَ ثَلَاثًا ثَلَاثًا. رَوَاهُ مُسلم
‘Uthman performed ablution in places where people sat and said, “Shall I not show you how God’s messenger performed ablution?” He then performed each detail thrice. Muslim transmitted it.
