Musnad Ahmad 1153:482

Abdullah ibn Ahmad said: I found this hadith in my father’s book in his own handwriting: Ubaydullah ibn Muhammad al-Taymi, who is al-Ayshi, narrated to us, saying: Hammad informed us, from Hisham ibn Urwah, from Urwah, from Aisha, that the Messenger of Allah, peace and blessings of Allah be upon him, said: "By the One in Whose hand is my soul, they are indeed weeping over him, and he is indeed being punished in his grave for his sin."
