Bulugh al-Maram 1 The Book of Purification كتاب الطهارة 61

وَعَنْ طَلْحَةَ بْنِ مُصَرِّفٍ, عَنْ أَبِيهِ, عَنْ جَدِّهِ قَالَ: { رَأَيْتُ رَسُولَ اَللَّهِ – صلى الله عليه وسلم -يَفْصِلُ بَيْنَ اَلْمَضْمَضَةِ وَالِاسْتِنْشَاقِ. } أَخْرَجَهُ أَبُو دَاوُدَ بِإِسْنَادِ ضَعِيف ٍ 1 . 1 – ضعيف. رواه أبو داود (139).

Narrated Talha bin Musarrif, quoting his father on the authority of his grandfather: “I saw Allah’s Messenger (صلى الله عليه وسلم) rinsing his mouth and sniffing up and blowing his nose with separate scops of water.” [Reported by Abu Da’ud with a weak chain of narrators].
