The Book of the Times (of Prayer) — Hadith #524
أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا أَبُو دَاوُدَ، حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، قَالَ سَمِعْتُ أَبَا أَيُّوبَ الأَزْدِيَّ، يُحَدِّثُ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو، - قَالَ شُعْبَةُ كَانَ قَتَادَةُ يَرْفَعُهُ أَحْيَانًا وَأَحْيَانًا لاَ يَرْفَعُهُ - قَالَ
" وَقْتُ صَلاَةِ الظُّهْرِ مَا لَمْ تَحْضُرِ الْعَصْرُ وَوَقْتُ صَلاَةِ الْعَصْرِ مَا لَمْ تَصْفَرَّ الشَّمْسُ وَوَقْتُ الْمَغْرِبِ مَا لَمْ يَسْقُطْ ثَوْرُ الشَّفَقِ وَوَقْتُ الْعِشَاءِ مَا لَمْ يَنْتَصِفِ اللَّيْلُ وَوَقْتُ الصُّبْحِ مَا لَمْ تَطْلُعِ الشَّمْسُ " .
“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.”
