Musannaf Ibn Abi Shayba 16:382

Abu Bakr narrated to us, he said: Waki’ narrated to us, from Ibn Abi Rawwad, from Nafi’, from Ibn ‘Umar: That he had *Jallalah* (animals that eat filth) camels, so he sent them away to the *Hima* (protected pasture land), then he brought them back and loaded riding saddles upon them to Makkah.
