ذِكْرُ الْإِبَاحَةِ لِلْمَرْءِ أَنْ يَقْتَصِرَ فِي الْوُضُوءِ عَلَى مَرَّةٍ مَرَّةٍ إِذَا أَسْبَغَ
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)
«أَنَا أَعْلَمُكُمْ بِوُضُوءِ رَسُولِ اللَّهِ ﷺ فَتَوَضَّأَ مَرَّةً مَرَّةً»
