Abu Huraira reported Allah’s Apostle (may peace be upon him) 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.

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.
