Musnad Ahmad 1153:1688

Waki' narrated to us, al-A'mash narrated to us, from Abu Wa'il, from Masruq, from Aisha, who said: A Jewish woman entered upon me and mentioned the punishment of the grave. I denied it. Then the Messenger of Allah (peace and blessings of Allah be upon him) entered upon me, and I asked him. He said: "She spoke the truth. By the One in Whose hand is my soul, they are indeed punished in their graves to the extent that the beasts hear their voices."
