Narrated Abu Hurairah:The Apostle of Allaah ( sal Allaahu alayhi wa sallam ) as saying: I am like father to you. When any of you goes to privy, he should not face or turn his back towards the qiblah. He should not cleanse with his right hand. He (the Prophet, sal Allaahu alayhi wa sallam) also commanded the Muslims to use three stones and forbade them to use dung or decayed bone
