Alqama bin Mrthd علقمة بن مرثد · The Book of the Times (of Prayer)

"Sometimes he (Qatadah, his teacher) narrated it as a Marfu' report and sometimes he did not" - "The time for Zuhr prayer is until 'Asr comes, and the time for 'Asr prayer is until the sun turns yellow. the time for Maghrib is until the twilight disappears, and the time for 'Isha' is until the night is halfway through, and the time for Subh is until the sun rises."
