Musnad Ahmad 28:488

'Abd al-Samad narrated to us, Hammam narrated to us, Qatadah narrated to us, from Abu Ayyub, from 'Abdullah ibn 'Amr, that the Messenger of Allah (ﷺ) said: "The time for Dhuhr is when the sun has passed the meridian and a man's shadow is equal to his height, as long as the time for 'Asr has not arrived. The time for 'Asr is as long as the sun has not turned yellow. The time for Maghrib prayer is as long as the twilight has not disappeared. The time for 'Isha prayer is until the middle of the night. The time for the morning prayer (Subh) is from the breaking of dawn, as long as the sun has not risen. So when the sun rises, refrain from prayer, for it rises between the two horns of a devil."
