وَحَدَّثَنِى أَحْمَدُ بْنُ يُوسُفَ الأَزْدِىُّ حَدَّثَنَا عُمَرُ بْنُ عَبْدِ اللَّهِ بْنِ رَزِينٍ حَدَّثَنَا إِبْرَاهِيمُ - يَعْنِى ابْنَ طَهْمَانَ - عَنِ الْحَجَّاجِ - وَهُوَ ابْنُ حَجَّاجٍ - عَنْ قَتَادَةَ عَنْ أَبِى أَيُّوبَ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرِو بْنِ الْعَاصِ أَنَّهُ قَالَ سُئِلَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- عَنْ وَقْتِ الصَّلَوَاتِ فَقَالَ « وَقْتُ صَلاَةِ الْفَجْرِ مَا لَمْ يَطْلُعْ قَرْنُ الشَّمْسِ الأَوَّلُ وَوَقْتُ صَلاَةِ الظُّهْرِ إِذَا زَالَتِ الشَّمْسُ عَنْ بَطْنِ السَّمَاءِ مَا لَمْ يَحْضُرِ الْعَصْرُ وَوَقْتُ صَلاَةِ الْعَصْرِ مَا لَمْ تَصْفَرَّ الشَّمْسُ وَيَسْقُطْ قَرْنُهَا الأَوَّلُ وَوَقْتُ صَلاَةِ الْمَغْرِبِ إِذَا غَابَتِ الشَّمْسُ مَا لَمْ يَسْقُطِ الشَّفَقُ وَوَقْتُ صَلاَةِ الْعِشَاءِ إِلَى نِصْفِ اللَّيْلِ ».

It was narrated from 'Abdullah bin 'Amr bin Al-As that he said: "The Messenger of Allah (s.a.w) was asked about the times of prayer. He said: 'The time for the Fajr prayer is so long as the first part of the sun has not risen. The time for the Zuhr prayer is from when the sun passes the middle of the sky, so long as 'Asr has not come. The time for the 'Asr prayer is so long as the sun has not turned yellow and the first part of it has not disappeared. The time for the Maghrib prayer is when the sun sets, so long as the twilight has not disappeared. The time for 'Isha' prayer is until halfway through the night.'"
