Sahih Muslim Book - 5, Hadith - 1388

وَحَدَّثَنِى أَحْمَدُ بْنُ إِبْرَاهِيمَ الدَّوْرَقِىُّ حَدَّثَنَا عَبْدُ الصَّمَدِ حَدَّثَنَا هَمَّامٌ حَدَّثَنَا قَتَادَةُ عَنْ أَبِى أَيُّوبَ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو أَنَّ رَسُولَ اللَّهِ -صلى الله عليه وسلم- قَالَ « وَقْتُ الظُّهْرِ إِذَا زَالَتِ الشَّمْسُ وَكَانَ ظِلُّ الرَّجُلِ كَطُولِهِ مَا لَمْ يَحْضُرِ الْعَصْرُ وَوَقْتُ الْعَصْرِ مَا لَمْ تَصْفَرَّ الشَّمْسُ وَوَقْتُ صَلاَةِ الْمَغْرِبِ مَا لَمْ يَغِبِ الشَّفَقُ وَوَقْتُ صَلاَةِ الْعِشَاءِ إِلَى نِصْفِ اللَّيْلِ الأَوْسَطِ وَوَقْتُ صَلاَةِ الصُّبْحِ مِنْ طُلُوعِ الْفَجْرِ مَا لَمْ تَطْلُعِ الشَّمْسُ فَإِذَا طَلَعَتِ الشَّمْسُ فَأَمْسِكْ عَنِ الصَّلاَةِ فَإِنَّهَا تَطْلُعُ بَيْنَ قَرْنَىْ شَيْطَانٍ ».

It was narrated from 'Abdullah bin 'Amr that the Messenger of Allah (s.a.w) said: "The time for Zuhr is when the sun passes its zenith and the shadow of a man is equal in length to him, so long as 'Asr has not come. The time of 'Asr is so long as the sun has not turned yellow. The time for the Maghrib prayer is so long as the twilight has not yet disappeared. The time for the 'Isha' prayer is until halfway through the night. The time for the Subh prayer is from dawn, so long as the sun has not yet risen. When the sun rises, then refrain from praying, for it rises between the horns of the Shaittan."
