Abu Huraira reported Allah's Apostle (ﷺ) as saying:When anyone wipes himself with pebbles (after answering the call of nature) he must make use of an odd number and when any one of you performs ablution he must snuff in his nose water and then clean it
قَالَ هَذَا مَا حَدَّثَنَا أَبُو هُرَيْرَةَ، عَنْ مُحَمَّدٍ، رَسُولِ اللَّهِ صلى الله عليه وسلم فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِذَا تَوَضَّأَ أَحَدُكُمْ فَلْيَسْتَنْشِقْ بِمَنْخِرَيْهِ مِنَ الْمَاءِ ثُمَّ لْيَنْتَثِرْ ".
Hammam b. Munabbih reported: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
أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَنْ تَوَضَّأَ فَلْيَسْتَنْثِرْ وَمَنِ اسْتَجْمَرَ فَلْيُوتِرْ ".
Abu Huraira reported:The Messenger of Allah (way peace he upon him) said: When anyone performs ablution he must clean his nose and when anyone wipes himself with pebbles (after answering the call of nature) he must do that odd number of times
It has been transmitted by Abu Huraira and Abu Sa'id al-Khudri (both of them the reputed Companions of the Holy Prophet) that the Messenger of Allah (ﷺ) said like that
