Musnad Ahmad 25:937

Yunus narrated to us, Hammad narrated to us, from Abdullah ibn Uthman ibn Khuthaym, from Sa'id ibn Jubayr, from Ibn Abbas, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "The Stone shall surely be resurrected on the Day of Resurrection; it will have two eyes with which it sees, and a tongue with which it speaks, and it will bear witness for whoever touched it in truth."
