Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that we set out from Mina to Arafat in the morning with the Messenger of Allah (peace and blessings be upon him), and some of us were proclaiming the Talbiyah and some were reciting the Takbeer. Imam Abu Bakr (may Allah have mercy on him) says that to my knowledge, among the narrators who reported this narration from Yahya bin Saeed, none mentioned Abdullah bin Abdullah bin Umar in this chain except Ibn Numair. I have mentioned all the routes of this narration in Kitab al-Kabir.
