Musannaf Ibn Abi Shayba 18:340

Abu Bakr narrated to us, he said: Yazid bin Harun narrated to us, from Sa’id, from Qatada, from ‘Abdullah bin Burayda, from Yahya bin Ya’mur, from Ibn ‘Abbas, from ‘Umar regarding the blind eye: if it is gouged out and it was upright (intact), then its blood money is one-third.
