Musnad Ahmad 5:734

Abdullah narrated to us, Nasr ibn Ali narrated to me, Abdullah ibn Dawud narrated to us, from Nu'aym ibn Hakim, from Abu Maryam, from Ali, who said: "There were idols upon the Kaaba. I went to carry the Prophet, may Allah bless him and grant him peace, up to them, but I could not. So he carried me, and I began to cut them down. And had I wished, I could have reached the sky."
