Seriously, what do Muslims do when they go to the bathroom? Do they not use toilet paper or its equivalent?
Clean yourself with an odd number of stones[edit]
Narrated Abu Huraira: The Prophet said, “Whoever performs ablution should clean his nose with water by putting the water in it and then blowing it out, and whoever cleans his private parts with stones should do it with odd number of stones.”
Sahih Bukhari 1:4:162
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.
Sahih Muslim 2:458
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.
Sahih Muslim 2:460
Jabir b. ‘Abdullah reported that he heard the Messenger of Allah (may peace be upon him) say: When anyone wipes himself with pebbles (after answering the call of nature) he should do this odd number of times.
