Takhrij Hadith 1798: "I am to you like…"

I am to you like a father: I teach you. So when any one of you goes to relieve himself, he should neither face the Qiblah nor turn his back toward it. He should not clean himself with his right hand. He would also instruct that three stones be used, and he forbade the use of dung and dry bones (for cleansing).
