Dawud ibn ‘Amr narrated to us, Nafi‘ ibn ‘Umar ibn Jamil al-Jumahi narrated to us, he said: I saw ‘Ata’, Ibn Abi Mulaykah, and ‘Ikrimah ibn Khalid “stoning the Jamrah before dawn on the Day of Sacrifice.” ‘Abdullah ibn Ahmad said: My father said to him, “O Abu Sulayman, in which year did you hear from Nafi‘ ibn ‘Umar?” He said, “The year sixty-nine, the year of the event of al-Husayn.”
