Musnad Ahmad 30:589

'Abd al-Razzaq narrated to us, Ma'mar informed us, from Ibn Tawus, from his father, from Abu Hurayrah, and from Hammam ibn Munabbih, from Abu Hurayrah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "We are the last, the foremost on the Day of Resurrection, except that they were given the Book before us, and we were given it after them. This is their day which was ordained for them, but they differed concerning it, so Allah guided us to it. They are followers to us in it; the Jews are tomorrow, and the Christians are the day after tomorrow."
