Musnad Ahmad 962:136

Muhammad ibn Yazid al-Wasiti narrated to us, from Uthman ibn Abi al-Atikah, from al-Qasim Abu Abd al-Rahman, from Abu Umamah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "A prayer [performed] immediately after a prayer—Abdullah ibn Ahmad said: My father said: And others said: 'in the wake of a prayer'—with no idle talk between them, is a record in 'Illiyyun." Abdullah said: I said to my father: From where did Muhammad ibn Yazid hear from Uthman ibn Abi al-Atikah? He said: His origin was Levantine; he heard from him in the Levant.
