Imam Ibnu Majah : 399حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ حَدَّثَنَا أَبُو الْحُسَيْنِ الْعُكْلِيُّ عَنْ خَالِدِ بْنِ عَبْدِ اللَّهِ عَنْ عَمْرِو بْنِ يَحْيَى عَنْ أَبِيهِ عَنْ عَبْدِ اللَّهِ بْنِ زَيْدٍ الْأَنْصَارِيِّ قَالَأَتَانَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَسَأَلَنَا وَضُوءًا فَأَتَيْتُهُ بِمَاءٍ فَمَضْمَضَ وَاسْتَنْشَقَ مِنْ كَفٍّ وَاحِدٍ
Narrated to us Ali bin Muhammad, narrated to us Abu Al Husain Al Ukli, from Khalid bin Abdullah, from Amru bin Yahya, from his father, from Abdullah bin Zaid Al Anshari, he said: 'The Messenger of Allah (peace and blessings be upon him) came to us and asked for wudhu water. We brought him water, and he rinsed his mouth and sniffed water into his nose with one handful.'
