Messenger of Allah said: "Indeed for (the time of) Salat (there is a) beginning and an end. The beginning of the time for the Zuhr prayer is when the sun passes the zenith, and the end of its time is when the time for Asr enters. The beginning of the time for the Asr [prayer] is when its time enters, and the end of its time is when the sun yellows (turns pale). The beginning of the time of Maghrib is when the sun as set, and the end of its time is when the twilight has vanished (i.e., the horizon is invisible because of darkness). The beginning of the time for Isha, the later one, is when the horizon has vanished, and the end of its time is when the night is at its half. The beginning of the time for Fajr is when Fajr begins, and its end is when the sun rises." (Using translation from Tirmidhī 151)  

قَالَ رَسُولُ اللهِ ﷺ إِنَّ لِلصَّلَاةِ أَوَّلًا وَآخِرًا وَإِنَّ أَوَّلَ وَقْتِ الظُّهْرِ حِينَ تَزُولُ الشَّمْسُ وَإِنَّ آخِرَ وَقْتِهَا حِينَ يَدْخُلُ وَقْتُ الْعَصْرِ وَإِنَّ أَوَّلَ وَقْتِ الْعَصْرِ حِينَ يَدْخُلُ وَقْتُهَا وَإِنَّ آخِرَ وَقْتِهَا حِينَ تَصْفَرُّ الشَّمْسُ وَإِنَّ أَوَّلَ وَقْتِ الْمَغْرِبِ حِينَ تَغْرُبُ الشَّمْسُ وَإِنَّ آخِرَ وَقْتِهَا حِينَ يَغِيبُ الْأُفُقُ وَإِنَّ أَوَّلَ وَقْتِ الْعِشَاءِ الْآخِرَةِ حِينَ يَغِيبُ الْأُفُقُ وَإِنَّ آخِرَ وَقْتِهَا حِينَ يَنْتَصِفُ اللَّيْلُ وَإِنَّ أَوَّلَ وَقْتِ الْفَجْرِ حِينَ يَطْلُعُ الْفَجْرُ وَإِنَّ آخِرَ وَقْتِهَا حِينَ تَطْلُعُ الشَّمْسُ  

[Machine] The Messenger of Allah ﷺ said, "Indeed, the prayer has a beginning and an end. The first time for the Dhuhr prayer is when the sun starts to decline, and the last time is when the time for Asr prayer begins. The first time for Asr prayer is when its time starts, and the last time is when the sun turns yellow. The first time for Maghrib prayer is when the sun sets, and the last time is when the horizon disappears. The first time for Isha prayer is when the horizon disappears, and the last time is when the night is halfway through. The first time for Fajr prayer is when the dawn breaks, and the last time is when the sun rises." Abu Abdullah Al-Hafiz narrated to us, Abu Al-Abbas Muhammad Ibn Ya'qub said, "I heard Al-Abbas Ibn Muhammad Ad-Duri say, 'I heard Yahya Ibn Ma'een saying that Muhammad Ibn Fudayl weakens the hadith narrated from Al-Amash through Abu Saleh from Abu Hurairah. I believe that Yahya intended to say that the prayer has a beginning and an end.' He also said, 'It is only narrated from Al-Amash through Mujahid.' And he said in another place in Al-Tareekh, 'The hadith of Al-Amash through Abu Saleh from Abu Hurairah said, "The Messenger of Allah ﷺ said, 'Indeed, the prayer has a beginning and an end.'"
