Musnad Ahmad 30:1766

Muhammad ibn Ubayd narrated to us, Ubayd Allah narrated to us, from Sa’id ibn Abi Sa’id, from Abu Hurayrah, that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Indeed, Allah the Almighty and Majestic has prohibited, upon my tongue, what is between the two lava fields of Medina." Then the sons of so-and-so came, and he said: "I do not see you but that you have exited the sanctuary." Then he looked and said: "Rather, you are within it; rather, you are within it." Muhammad ibn Ubayd said: Then the sons of Jariyah came, and they are only the sons of Harithah.
