Musnad Ahmad 403:3

Abdullah ibn Ahmad said: Mus'ab—meaning al-Zubayri—narrated to us, saying: Abd al-Aziz ibn Muhammad narrated to me, from Abd al-Rahman ibn al-Harith ibn Abdullah ibn Ayyash al-Makhzumi, from Ibn Shihab, from Ubayd Allah ibn Abdullah ibn Utbah ibn Mas'ud, from Abdullah ibn Abbas, from al-Sa'b ibn Jaththama al-Laythi, that the Messenger of Allah (may Allah bless him and grant him peace) declared al-Naqi' a protected area (hima). And he said: "There is no protection (hima) except for Allah and His Messenger."
