The Messenger of Allah rinsed his mouth and sniffed water up into his nostrils from one scoop of water.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الْجَرَّاحِ، وَأَبُو بَكْرِ بْنُ خَلاَّدٍ الْبَاهِلِيُّ حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ مُحَمَّدٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ مَضْمَضَ وَاسْتَنْشَقَ مِنْ غَرْفَةٍ وَاحِدَةٍ ‏.‏
