It has been narrated by Abdullah (b. Mas'ud) who said:
When the Messenger of Allah ( صلی اللہ علیہ وسلم ) was lying postrate in prayer and around him were some people from the Quraish, 'Uqba b. Abu Mu'ait brought the foetus of a she-camel and threw it on the back of the Messenger of Allah ( صلی اللہ علیہ وسلم ). He did not raise his head until Fatima arrived, removed it from his back and cured him who had done that (ugly act). He said: O Allah, it is for Thee to deal with the chiefs of the Quraish. Abu Jahl b. Hisham, 'Utba b. Rabi'a. Uqba b. Abu Mu'ait, Shaiba b. Rabi'a, Umayya b. Khalaf or Ubayy b. Khalaf (Shu'ba, one of the narrator of this tradition is in doubt about the exact person). I saw that all were slain in the Battle of Badr and their dead bodies were thrown into a well, except that of Umayya or Ubayy which was cut into pieces and was thrown into the well.
