Musnad Ahmad 1017:6

'Affan narrated to us, 'Abd al-'Aziz ibn Muslim narrated to us, he said: Abu Sinan narrated to us, from Muharib ibn Dithar, from Ibn Buraydah, from his father, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "The people of Paradise are one hundred and twenty rows, eighty of which are from this nation." And 'Affan said once: "You are eighty rows of them."
