Musnad Ahmad 535:3

Hassan ibn Musa narrated to us, Ibn Lahi'ah narrated to us, Sulayman ibn Ziyad narrated to us, from Abdullah ibn al-Harith ibn Juz' al-Zubaydi, who said: "We ate roasted meat with the Messenger of Allah, peace and blessings of Allah be upon him, in the mosque. Then the prayer was called, so we wiped our hands on the pebbles, then we stood to pray, and we did not perform ablution."
