Musannaf Ibn Abi Shayba 36:257

'Affan narrated to us, he said: Hammad ibn Salamah narrated to us, from Thabit, from Anas, from Abu Talhah, who said: I raised my head on the day of Uhud, and I began to look, and I did not see anyone among the people except that he was swaying under his shield from drowsiness.
