Musnad Abu Ya'la al-Mawsili 178:1

Al-Qawariri narrated to us, Abd al-Rahman ibn Mahdi narrated to us, from Malik ibn Anas, from Abdullah ibn Abi Bakr, from his father, from Abu al-Baddah ibn Asim ibn Adi, from his father: That the Messenger of Allah (peace be upon him) granted a concession to the shepherds to spend the night away from Mina. They would perform the stoning on the Day of Sacrifice (Yawm al-Nahr), and they would perform the stoning on the following day and after the two following days.
