Musannaf Ibn Abi Shaybah 3261 — All the prayer times

Sayyiduna Abdullah bin Amr (may Allah be pleased with him) said: The time of Zuhr lasts as long as the time of Asr has not come. The time of Asr lasts as long as the sun has not turned yellow. The time of Maghrib lasts as long as the twilight has not faded, and the time of Isha is until half the night. And the time of Fajr lasts as long as the sun has not risen.
