Rinsing the mouth and sniffing up water into the nostrils with one handful of water
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا أَبُو الْحُسَيْنِ الْعُكْلِيُّ، عَنْ خَالِدِ بْنِ عَبْدِ اللَّهِ، عَنْ عَمْرِو بْنِ يَحْيَى، عَنْ أَبِيهِ، عَنْ عَبْدِ اللَّهِ بْنِ زَيْدٍ الأَنْصَارِيِّ، قَالَ أَتَانَا رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ فَسَأَلَنَا وَضُوءًا فَأَتَيْتُهُ بِمَاءٍ فَمَضْمَضَ وَاسْتَنْشَقَ مِنْ كَفٍّ وَاحِدٍ .
It was narrated that 'Abdullah bin Zaid Al-Ansari said: "The Messenger of Allah (ﷺ) came to us and asked us for water for ablution. I brought water to him and he rinsed his mouth and sniffed water up into his nostrils from one handful."
