Musnad Ahmad 33:869

Muhammad ibn Ubayd narrated to us, Abd al-Malik narrated to us, from Abu al-Zubayr, from Jabir, who said: When Abdullah ibn Ubayy died, his son came to the Prophet, peace and blessings of Allah be upon him, and said: "O Messenger of Allah, if you do not come to him, we will never cease to be taunted for this." So the Prophet, peace and blessings of Allah be upon him, came to him and found that he had already been placed into his grave. He said: "Would you not have [waited] before you placed him in?" Then he was taken out of his grave, and he (the Prophet) spat upon him from his head to his feet, and he clothed him in his shirt.
