This is what Abu Huraira transmitted to us from Muhammad, the Messenger of Allah ﷺ, and he mentioned a number of a hadith, of which this is one: that the Messenger of Allah ﷺ said: When anyone amongst you (performs ablution) he must snuff his nostrils with water and then clean them.  

عَنْ مُحَمَّدٍ رَسُولِ اللَّهِ ﷺ فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ ﷺ إِذَا تَوَضَّأَ أَحَدُكُمْ فَلْيَسْتَنْشِقْ بِمَنْخِرَيْهِ مِنَ الْمَاءِ ثُمَّ لْيَنْتَثِرْ  

"When any one of you performs Wudu', let him put water in his nose then blow it out."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا تَوَضَّأَ أَحَدُكُمْ فَلْيَجْعَلْ فِي أَنْفِهِ مَاءً ثُمَّ لْيَسْتَنْثِرْ  

The Messenger of Allah ﷺ said: When any of you performs ablution, he should snuff up water in his nose and eject mucus.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا تَوَضَّأَ أَحَدُكُمْ فَلْيَجْعَلْ فِي أَنْفِهِ مَاءً ثُمَّ لْيَنْثُرْ  

Yahya related to me from Malik from Abu'zZinad from al-Araj from Abu Hurayra that the Messenger of Allah ﷺ said, "When you do wudu, snuff water into your nose and blow it out, and if you use stones to clean your private parts use an odd number."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا تَوَضَّأَ أَحَدُكُمْ فَلْيَجْعَلْ فِي أَنْفِهِ مَاءً ثُمَّ لِيَنْثِرْ وَمَنِ اسْتَجْمَرَ فَلْيُوتِرْ  

The Messenger of Allah ﷺ said: When any of you performs ablution, he should snuff up water in his nose and eject mucus. (Using translation from Abū Dāʾūd 140)  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ «إِذَا تَوَضَّأَ أَحَدُكُمْ فَلْيَجْعَلْ فِي أَنْفِهِ مَاءً ثُمَّ لِيَسْتَنْثِرْ»  

[Machine] From the Messenger of Allah ﷺ who said: "When one of you performs ablution, let them sniff water through their nostrils, and then let them blow it out."  

عَنْ رَسُولِ اللهِ ﷺ قَالَ إِذَا تَوَضَّأَ أَحَدُكُمْ فَلْيَسْتَنْشِقْ بِمَنْخِرَيْهِ مَاءً ثُمَّ لِيَنْثُرَ  

"إذَا توضَّأ أحدُكم فليَستَنْشِقْ بمنخريه من الماء، ثمَّ ليسْتنثرْ، وإذا اسْتَجْمر فليُوتِرْ" .
