Musnad Ahmad 26:412

Wahb ibn Jarir narrated to us, Shu'bah narrated to us, from Abu Ishaq, from 'Amr ibn Maymun, from 'Abdullah, who said: I did not see the Messenger of Allah, peace and blessings of Allah be upon him, invoke a curse against Quraysh except for one day. He was praying, and a group of Quraysh were sitting, and there was the placenta of a camel near him. They said: "Who will take this placenta and throw it onto his back?" 'Uqbah ibn Abi Mu'ayt said: "I will." So he took it and threw it onto his back. He remained prostrating until Fatimah, may the blessings of Allah be upon her, came and removed it from his back. The Messenger of Allah, peace and blessings of Allah be upon him, said: "O Allah, deal with the assembly of Quraysh. O Allah, deal with 'Utbah ibn Rabi'ah. O Allah, deal with Shaybah ibn Rabi'ah. O Allah, deal with Abu Jahl ibn Hisham. O Allah, deal with 'Uqbah ibn Abi Mu'ayt. O Allah, deal with Ubayy ibn Khalaf, or Umayyah ibn Khalaf." 'Abdullah said: "I saw them all killed on the day of Badr, then they were dragged to the pit, except for Ubayy or Umayyah, for he was a bulky man, so he fell apart."
