Hadith 357

Abu Huraira (may Allah be pleased with him) narrated that the Messenger of Allah (peace be upon him) said: "Whoever uses kohl (eye ointment) should perform odd-numbered acts of purification, and whoever does so has done well. If not, there is no harm. Whoever uses stones for cleaning after relieving himself should perform odd-numbered acts, and whoever does so has done well. If not, there is no harm. Whoever eats and finds something stuck between his teeth should spit it out, and whatever is chewed by his tongue should be swallowed. Whoever does so has done well, and if not, there is no harm. Whoever goes to relieve himself should cover himself. If he cannot find anything but a pile of sand, he should turn his back to it, for the devil plays with the private parts of the children of Adam. Whoever does so has done well, and if not, there is no harm."
