Musnad Abu Ya'la al-Mawsili 2:7

Hadb ibn Khalid narrated to us, Hammad ibn Salamah narrated to us, from Ali ibn Zayd, from Yusuf ibn Mihran, from Ibn Abbas, who said: I heard Umar ibn al-Khattab saying: "O people, do not be deceived regarding the stoning. Do not be deceived regarding the stoning, for the Messenger of Allah (peace and blessings of Allah be upon him) stoned, Abu Bakr stoned, and I have stoned. And there will be people who will deny the stoning, the intercession, the Dajjal, and a people who will emerge from the Fire after they have been scorched or have become scorched."
