Musannaf Ibn Abi Shayba 37:319

Mu'awiyah ibn Hisham narrated to us, he said: Sufyan narrated to us, from his father, from Abu Ya'la, from Ibn al-Hanafiyyah, that a people from before you became confused or divided until they wandered aimlessly. If one of them was called from behind him, he would answer from in front of him, and if he was called from in front of him, he would answer from behind him.
