Musnad Ahmad 1034:117

'Ali ibn 'Abdullah narrated to us, Mu'adh—meaning Ibn Hisham—narrated to us, he said: I found in my father's book in his own handwriting, and I did not hear it from him, from Qatadah, from Abu Ma'shar, from Ibrahim al-Nakha'i, from Hammam, from Hudhayfah, that the Prophet of Allah, peace and blessings of Allah be upon him, said: "In my nation, there are twenty-seven liars and impostors; among them are four women. And I am the Seal of the Prophets; there is no prophet after me."
