Narrated Ka`b bin 'Ujra: I came to the Prophet and he said to me, Come near. So I went near to him and he said, Are your lice troubling you? I replied, Yes. He said, (Shave your head and) make expiation in the form of fasting, Sadaqa (giving in charity), or offering a sacrifice. (The sub-narrator) Aiyub said, Fasting should be for three days, and the Nusuk (sacrifice) is to be a sheep, and the Sadaqa is to be given to six poor persons.
