'Abdullah b. Mughaffal reported God's messenger as saying, “No one must pass water where he bathes and then wash in it or perform ablution in it, for all evil promptings come from it.”
Abu Dawud transmitted it, as did Tirmidhi and Nasa’i, but they did not mention “then wash in it or perform ablution in 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.”
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.
