Musnad Abu Ya'la al-Mawsili 6:85

Zuhayr narrated to us, Ishaq ibn Isa narrated to us, Ibrahim ibn Sa’d narrated to us, from his father, from Mu’adh al-Taymi, who said: I heard Sa’d ibn Abi Waqqas saying: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Two prayers, there is no prayer after them: the morning [prayer] until the sun rises, and the afternoon [prayer] until the sun sets."
