Yahya related to me from Malik from Nafi that one timeAbdullah ibn Umar wanted to sacrifice an animal atMadina. Nafi said, "He told me to buy him an excellenthorned ram, then to sacrifice it on the Day of Sacrificein the place where the people prayed." Nafi continued, "Idid so and when the ram was sacrificed, it was carried toAbdullah ibn Umar who shaved his head. He was ill, anddid not attend the Id with the people." Nafi added,"Abdullah ibn Umar used to say, 'Shaving the head is notobligatory for someone who sacrifices an animal.' IbnUmar would do so however."
