Musannaf Ibn Abi Shayba 3:5143

Abu Bakr narrated to us, he said: Hatim ibn Isma'il narrated to us, from Anas ibn Abi Yahya, from his father, from Abu Sa'id al-Khudri, who said: A man from Banu Khudrah and a man from Banu 'Amr ibn 'Awf disputed regarding the mosque which was founded upon righteousness. The Khudri said: "It is the Mosque of the Messenger of Allah, may Allah bless him and grant him peace." And the 'Awfi said: "It is the Mosque of Quba." So they came to the Messenger of Allah, may Allah bless him and grant him peace, regarding that. He said: "It is this, it is this," meaning his mosque, "and in that is much good."
