Musannaf Ibn Abi Shayba 8:786

Abu Bakr narrated to us, he said: Abd al-Samad ibn Abd al-Warith narrated to us, from Hammad ibn Salamah, from Hisham ibn Urwah, from his father, that he used to begin, then throw at the head of the first Jamrah, and he would throw at its head. And he would throw at the Aqabah from where he drew near to it.
