Musnad Ahmad 535:8

Musa narrated to us, Ibn Lahi'ah narrated to us, from Khalid ibn Abi 'Imran and Sulayman ibn Ziyad al-Hadrami, from 'Abdullah ibn al-Harith ibn Juz' al-Zubaydi, who said: "We ate roasted meat with the Prophet, 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 up and prayed, and we did not perform ablution."
