Musnad Ahmad 623:6

Yazid ibn Harun narrated to us, Sa’id—meaning Ibn Abi ‘Aruba—informed us, from Qatadah, from Shahr ibn Hawshab, from ‘Abd al-Rahman ibn Ghanam, that ‘Amr ibn Kharijah al-Khushani narrated to them that the Prophet, peace and blessings of Allah be upon him, addressed them while upon his riding beast, and his riding beast was chewing its cud, and its saliva was flowing between its shoulders. He said: "Indeed, Allah has allotted to every person his share of the inheritance, so no bequest is permissible for an heir. The child is for the bed, and for the adulterer is the stone. Beware, whoever claims to be the son of someone other than his father, or claims loyalty to someone other than his masters, upon him is the curse of Allah, the angels, and all of mankind. Allah will not accept from him any obligatory deed nor any supererogatory deed."
