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