[Machine] On the authority of the Prophet ﷺ, he said: "The time for Dhuhr (noon) prayer is until the time of Asr (afternoon) prayer, and the time for Asr prayer is until the sun turns yellow, and the time for Maghrib (sunset) prayer is until the twilight disappears, and the time for Isha (night) prayer is until midnight, and the time for Fajr (dawn) prayer is until the sun rises."  

عَنِ النَّبِيِّ ﷺ قَالَ وَقْتُ الظُّهْرِ مَا لَمْ يَحْضُرِ الْعَصْرُ وَوَقْتُ الْعَصْرِ مَا لَمْ تَصْفَرَّ الشَّمْسُ وَوَقْتُ الْمَغْرِبِ مَا لَمْ يَسْقُطْ ثَوْرُ الشَّفَقِ وَوَقْتُ الْعِشَاءِ إِلَى نِصْفِ اللَّيْلِ وَوَقْتُ صَلَاةِ الْفَجْرِ مَا لَمْ تَطْلُعِ الشَّمْسُ  

Messenger of Allah ﷺ said, "Whoever could get one rakʿa (of the Fajr prayer) before sunrise, he has got the (morning) prayer and whoever could get one rakʿa of the ʿAsr prayer before sunset, he has got the (ʿAsr) prayer." (Using translation from Bukhārī 579)   

أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَنْ أَدْرَكَ رَكْعَةً مِنَ الصُّبْحِ قَبْلَ أَنْ تَطْلُعَ الشَّمْسُ فَقَدْ أَدْرَكَ الصُّبْحَ وَمَنْ أَدْرَكَ رَكْعَةً مِنَ الْعَصْرِ قَبْلَ أَنْ تَغْرُبَ الشَّمْسُ فَقَدْ أَدْرَكَ الْعَصْرَ لَفْظُ حَدِيثِ ابْنِ وَهْبٍ مُخَرَّجٌ فِي الصَّحِيحَيْنِ مِنْ حَدِيثِ مَالِكٍ  

If anyone says a rak'ah of the 'Asr prayer before sunset, he has observed (the 'Asr prayer), and if anyone performs a rak'ah of the Fajr prayer, he has observed (the Fajr prayer). (Using translation from Abū Dāʾūd 412)   

قَالَ رَسُولُ اللهِ ﷺ مَنْ أَدْرَكَ مِنَ الْعَصْرِ رَكْعَةً قَبْلَ أَنْ تَغْرُبَ الشَّمْسُ فَقَدْ أَدْرَكَ وَمَنْ أَدْرَكَ مِنَ الْفَجْرِ رَكْعَةً قَبْلَ أَنْ تَطْلُعَ الشَّمْسُ فَقَدْ أَدْرَكَ لَفْظُ حَدِيثِ أَبِي الْعَبَّاسِ
