Musnad Ahmad 27:1268

Yunus ibn Muhammad narrated to us, Layth narrated to us, from Muhammad ibn ‘Ajlan, from Zayd ibn Aslam, that he narrated to him that ‘Abdullah ibn ‘Umar came to Ibn Muti‘ during the nights of al-Harrah. He said: "Place a cushion for Abu ‘Abd al-Rahman." He said: "I did not come to sit; I only came to tell you two words I heard from the Messenger of Allah, peace and blessings of Allah be upon him. I heard the Messenger of Allah, peace and blessings of Allah be upon him, say: 'Whoever withdraws a hand from obedience, there will be no argument for him on the Day of Resurrection, and whoever dies while separating from the community, he dies the death of the Age of Ignorance (Jahiliyyah).'"
