Musannaf Ibn Abi Shayba 19:508

Abu Bakr narrated to us, he said: Muhammad bin Bakr narrated to us, from Ibn Jurayj, from ‘Ata’, who says: It was the practice of those who passed away that the thief would be brought, and it would be said to him: "Did you steal?" He would say: "No." And I do not know except that he named Abu Bakr and ‘Umar.
