Musannaf Ibn Abi Shayba 36:208

Abu Bakr narrated to us, he said: Jarir ibn Abd al-Hamid narrated to us, from Ata ibn al-Sa’ib, from al-Sha’bi, who said: The Messenger of Allah (may Allah bless him and grant him peace) used stratagem against the polytheists on the day of Uhud, and it was the first day he used stratagem against them.
