Musnad Abu Ya'la al-Mawsili 139:10

Ishaq ibn Abi Isra'il narrated to us, he said: Yahya ibn Ghaylan narrated to me, from Yazid ibn Zuray', from Sulayman al-Taymi, from Anas, who said: The Prophet, peace and blessings of Allah be upon him, only gouged out their eyes because they had gouged out the eyes of the shepherds.
