Musnad Ahmad 32:1581

Abu Sa'id narrated to us, Sulayman—meaning Ibn Bilal—narrated to us, from 'Amr ibn Abi 'Amr, from Anas ibn Malik, that the Messenger of Allah (peace and blessings of Allah be upon him) was returning from Khaybar. When he saw Uhud, he said: "This is a mountain that loves us and we love it." When he overlooked Medina, he said: "O Allah, I declare sacred what is between its two lava fields, just as Ibrahim declared Mecca sacred."
