Musannaf Ibn Abi Shayba 3:4271

Abu Bakr narrated to us, he said: Hushaym narrated to us, he said: Abu Bishr informed us, from Sa'id ibn al-Musayyib, who said: If I were to pray in my house, then come to a congregational mosque and catch one rak'ah with them, it would be more beloved to me than the prayer I prayed alone.
