May I not tell you how the Messenger of Allah ﷺ performed ablution? He then performed ablution washing each limb once only. (Using translation from Abū Dāʾūd 138)   

أَلَا أُنَبِّئُكُمْ أَوْ أَلَا أُخْبِرُكُمْ بِوُضُوءِ رَسُولِ اللَّهِ ﷺ؟ فَتَوَضَّأَ مَرَّةً مَرَّةً أَوْ قَالَ مَرَّةً مَرَّةً  

[Machine] The Prophet ﷺ used to perform ablution (wudu) by rinsing his mouth and nose together.  

أَنَّ النَّبِيَّ ﷺ «تَوَضَّأَ مَرَّةً مَرَّةً وجَمَعَ بَيْنَ الْمَضْمَضَةِ وَالِاسْتِنْشَاقِ»
