كتاب الصلاة
Read the English translation first, with the original Arabic directly underneath.
'Abd Allah b. 'Amr reported the Prophet (ﷺ) as saying:
The time of the Zuhr prayer is as along as the time of the 'Asr prayer has not come; the time of the Asr prayer is as long as the sun has not become yellow ; the time of the Maghrib prayer is as long as the twilight has not ended; the time of the Isha prayer is up to midnight; and the time of the Fajr prayer is as long as the sun has not risen.
وَقْتُ الظُّهْرِ مَا لَمْ تَحْضُرِ الْعَصْرُ وَوَقْتُ الْعَصْرِ مَا لَمْ تَصْفَرَّ الشَّمْسُ وَوَقْتُ الْمَغْرِبِ مَا لَمْ يَسْقُطْ فَوْرُ الشَّفَقِ وَوَقْتُ الْعِشَاءِ إِلَى نِصْفِ اللَّيْلِ وَوَقْتُ صَلاَةِ الْفَجْرِ مَا لَمْ تَطْلُعِ الشَّمْسُ
