[Machine] I was a new arrival among the Banu Al-Muntafiq when I came to the Messenger of Allah ﷺ and said, "O Messenger of Allah, inform me about ablution." He said, "Complete the ablution, run your fingers through your toes, and exaggerate in inhaling water during the sniffing [water into the nostril], except for when you are fasting." This narration is witnessed by Ibn Abbas.  

الحاكم:٥٢٥ – فَحَدَّثَنَا أَبُو بَكْرِ بْنُ إِسْحَاقَ الْفَقِيهُ أَنْبَأَ إِسْمَاعِيلُ بْنُ قُتَيْبَةَ ثنا يَحْيَى بْنُ يَحْيَى أَنْبَأَ يَحْيَى بْنُ سُلَيْمٍ عَنْ إِسْمَاعِيلَ بْنِ كَثِيرٍ قَالَ سَمِعْتُ عَاصِمَ بْنَ لَقِيطِ بْنِ صَبِرَةَ يُحَدِّثُ عَنْ أَبِيهِ قَالَ

كُنْتُ وَافِدَ بَنِي الْمُنْتَفِقِ إِلَى رَسُولِ اللَّهِ ﷺ فَقُلْتُ يَا رَسُولَ اللَّهِ أَخْبَرَنِي عَنِ الْوُضُوءِ فَقَالَ «أَسْبِغِ الْوُضُوءَ وَخَلِّلْ بَيْنَ الْأَصَابِعِ وَبَالِغْ فِي الِاسْتِنْشَاقِ إِلَّا أَنْ تَكُونَ صَائِمًا» وَلِهَذَا الْحَدِيثِ شَاهِدٌ عَنِ ابْنِ عَبَّاسٍ

[Machine] I came to the Messenger of Allah ﷺ as a newcomer from the Bani Al-Muntafiq tribe, and I said, "O Messenger of Allah, tell me about ablution." He said, "Perform the ablution thoroughly, separate between the fingers, and thoroughly inhale water during rinsing the nose unless you are fasting and the time for the forenoon prayer has passed. In a hadith narrated by Shu'ayb ibn Salamah, it is mentioned about the description of the Prophet's ﷺ ablution that he also separated between his toes."
