Musnad Ahmad 1153:169

Abu Mu'awiyah narrated to us, he said: Al-A'mash narrated to us, from Shaqiq, from Masruq, from Aisha, she said: A Jewish woman entered upon her and asked her for a gift of perfume, so Aisha gave her a gift. She said: "May Allah protect you from the punishment of the grave." She said: So that fell into my heart, until the Messenger of Allah (peace and blessings of Allah be upon him) came. She said: So I mentioned that to him, and I said: "O Messenger of Allah, is there a punishment in the grave?" He said: "Yes, they are indeed punished in their graves with a punishment that the beasts hear."
