Narrated Ruwayfi ibn Thabit: Shayban al-Qatbani reported that Maslamah ibn Mukhallad made Ruwayfi ibn Thabit the governor of the lower parts (of Egypt). He added: We travelled with him from Kum Sharik to Alqamah or from Alqamah to Kum Sharik (the narrator doubts) for Alqam. Ruwayfi said: Any one of us would borrow a camel during the lifetime of the Prophet ﷺ from the other, on condition that he would give him half the booty, and the other half he would retain himself. Further, one of us received an arrowhead and a feather, and the other an arrow-shaft as a share from the booty. He then reported: The Messenger of Allah ﷺ said: You may live for a long time after I am gone, Ruwayfi, so, tell people that if anyone ties his beard or wears round his neck a string to ward off the evil eye, or cleanses himself with animal dung or bone, Muhammad has nothing to do with him.

Narrated Salman al-Farsi: It was said to Salman: Your Prophet teaches you everything, even about excrement. He replied: Yes. He has forbidden us to face the qiblah at the time of easing or urinating, and cleansing with right hand, and cleansing with less than three stones, or cleansing with dung or bone.

Narrated Abu Hurairah: The Messenger of Allah ﷺ 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, ﷺ) also commanded the Muslims to use three stones and forbade them to use dung or decayed bone.

Narrated Khuzaymah ibn Thabit: The Prophet ﷺ was asked about cleansing (after relieving oneself). He said: (One should cleanse oneself) with three stones which should be free from dung. Abu Dawud said: A similar tradition has been narrated by Abu Usamah and Ibn Numair from Hisham.
