Musannaf Ibn Abi Shayba 3:4994

Abu Mu'awiyah narrated to us, from al-Shaybani, from 'Amr ibn Murrah, who said: Sa'id ibn al-Musayyib saw me while I was praying some of what I had missed of the night prayer after the dawn had broken. He said: "Do you not know that prayer is disliked at this hour, except for the two rak'ahs before the dawn prayer?"
