حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى، قَالَ: حَدَّثَنَا أَسَدَ بْنُ مُوسَى، قَالَ: ثنا ابْنُ أَبِي ذِئْبٍ، عَنْ قَارِظِ بْنِ شَيْبَةَ، عَنْ أَبِي غَطْفَانَ، قَالَ: دَخَلْتُ عَلَى ابْنِ عَبَّاسٍ رَضِيَ اللهُ عَنْهُمَا فَوَجَدْتُهُ يَتَوَضَّأُ فَمَضْمَضَ وَاسْتَنْشَقَ ثُمَّ قَالَ: قَالَ النَّبِيُّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ: «اسْتَنْثِرُوا ثِنْتَيْنِ بَالِغَتَيْنِ أَوْ ثَلَاثًا».
Abu Ghatfan (may Allah have mercy on him) says that I went to Abdullah bin Abbas (may Allah be pleased with them), and found him performing ablution. He rinsed his mouth, put water in his nose, and said: The Noble Prophet (peace and blessings be upon him) said: Clean your nose thoroughly two or three times.
