Anas said, "When God’s messenger entered the privy, a servant and I used to carry a skin of water and a pointed staff, and he would cleanse himself with the water.”
Abu Huraira reported God’s messenger as saying, "When anyone performs ablution he must clear his nose, and when anyone wipes himself with stones he must make use of an odd number.”
Anas said that when the Prophet entered the privy he took off his ring.
Abu Dawud, Nasa’i and Tirmidhi transmitted it. Tirmidhi said this is a hasan sahih gharib tradition, and Abu Dawud said this is a rejected (munkar) tradition. His version has "laid down” instead of "took off".
Abu Qatada reported God’s messenger as saying, "When one of you drinks he must not breathe into the vessel, and when he goes to relieve himself he must not touch his penis with his right hand, or wipe himself with his right hand.”
