Musannaf Ibn Abi Shayba 36:204

Waki' narrated to us, he said: Isra'il narrated to us, from Abu Ishaq, from Abu 'Ubaydah, from 'Abdullah, who said: We partnered on the day of Badr—myself, 'Ammar, and Sa'd—in what we obtained on the day of Badr. As for myself and 'Ammar, we did not bring anything, and Sa'd brought two captives.
