Musnad Ahmad 27:1260

'Abd al-Samad narrated to us, Hammad narrated to us, Khalid al-Hadhdha' narrated to us, that Abu al-Malih said to Abu Qilabah: I and your father entered upon Ibn 'Umar, and he narrated to us that he entered upon the Messenger of Allah, may Allah bless him and grant him peace. He (the Prophet) threw a cushion of tanned leather for him, the stuffing of which was palm fiber. I did not sit upon it; it remained between me and him.
