Ibn Mas'ud reported God’s messenger as saying, “Do not cleanse yourselves with excrement or bones, for that is the provision of your brethren among the jinn.”
Tirmidhi transmitted it, as also Nasa'i, but he did not mention “the provision of your brethren among the jinn.”
Ruwaifi' b. Thabit told that God’s messenger said to him, “You may live for a long time after I am gone, Ruwaifi', 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.
She also reported God’s messenger as saying, “When one of you goes to relieve himself he should take with him three stones with which to cleanse himself, for they will be enough for him.”
Ahmad, Abu Dawud, Nasa’i and Darimi transmitted it.
Abu Huraira reported God’s messenger as saying, “If anyone applies collyrium he should do it an odd number of times. If one does so he has done well, but if not, there is no harm. If anyone cleanses himself with stones he should make use of an odd number. If one does so he has done well, but if not, there is no harm. If anyone eats he should throw away what he removes with a toothpick and swallow what he removes with his tongue. If one does so he has done well, but if not, there is no harm. If one goes to relieve himself he should conceal himself, and if all he can do is to collect a heap of sand he should sit with his back to it, for the devil makes sport with the posteriors of the children of Adam. If one does so he has done well, but if not, there is no harm.”
