Musnad Ahmad 25:1218

'Abd al-Razzaq narrated to us, he said: Ma'mar said: And 'Abd al-Karim al-Jazari informed me, from Sa'id ibn Jubayr, from Ibn 'Abbas: That a man fell from a camel of his while he was in the state of ihram, and it broke his neck (or: he suffered a broken neck), then he mentioned the like of the hadith of Ayyub.
