Musnad Ahmad 31:899

'Abd al-Razzaq and Ibn Bakr narrated to us, they said: Ibn Jurayj informed us, he said: And Ibn Shihab narrated to me, from 'Ata' ibn Yazid al-Jund'i, that he heard Abu Sa'id al-Khudri saying: I heard the Messenger of Allah, peace and blessings of Allah be upon him, saying: "There is no prayer after the morning prayer until the sun rises" — and Ibn Bakr said: "until the sun ascends" — "and there is no prayer after the afternoon prayer until the sun sets."
