Musnad Ahmad 32:568

Ishaq narrated to us, Malik narrated to me, from Amr, the freed slave of al-Muttalib, from Anas ibn Malik, that Mount Uhud appeared to the Messenger of Allah, may Allah bless him and grant him peace, and he said: "This is a mountain that loves us and we love it. O Allah, indeed Ibrahim declared Makkah sacred, and I declare sacred what is between its two lava fields."
