Musnad Ahmad 25:784

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