عَنْ أَبِي غَطْفَانَ قَالَ: دَخَلْتُ عَلَى ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُ فَوَجَدْتُهُ يَتَوَضَّأُ فَتَمَضْمَضَ وَاسْتَنْشَقَ ثُمَّ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((اسْتَنْثِرُوهُ ثِنْتَيْنِ (وَفِي رِوَايَةٍ: مَرَّتَيْنِ بَالِغَتَيْنِ أَوْ ثَلَاثًا)))
Abu Ghatfan, may Allah have mercy on him, says: I went to Sayyiduna Abdullah bin Abbas, may Allah be pleased with them both, he was performing ablution, he rinsed his mouth and put water into his nose and then said: The Messenger of Allah, peace and blessings be upon him, said: "Blow your nose twice," (in another narration: "Blow it well two or three times").
