حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا شَرِيكٌ، عَنْ خَالِدِ بْنِ عَلْقَمَةَ، عَنْ عَبْدِ خَيْرٍ، عَنْ عَلِيٍّ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ تَوَضَّأَ فَمَضْمَضَ ثَلاَثًا وَاسْتَنْشَقَ ثَلاَثًا مِنْ كَفٍّ وَاحِدٍ .
It was narrated from 'Ali that: The Messenger of Allah performed ablution and he rinsed his mouth three times, and sniffed water up into his nose three times from one handful.
