‘Uthman b. ‘Affan reported the Messenger of Allah (may peace be him) as saying; if anyone says the night prayer in congregation, he is like one who keeps vigil (in prayer) till midnight; and he who says both the night and dawn prayer in congregation is like one who keeps vigil (in prayer) the whole night.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ صَلَّى الْعِشَاءَ فِي جَمَاعَةٍ كَانَ كَقِيَامِ نِصْفِ لَيْلَةٍ وَمَنْ صَلَّى الْعِشَاءَ وَالْفَجْرَ فِي جَمَاعَةٍ كَانَ كَقِيَامِ لَيْلَةٍ  

The Messenger of Allah ﷺ said:Whoever prays ʿIshaʿ in congregation, it will be like spending half the night in prayer (qiyam) and whoever prays ʿIshaʿ and Fajr in congregation, it will be like spending the whole night in prayer.ʿ (Using translation from Aḥmad 491)  

قَالَ رَسُولُ اللَّهِ ﷺ «مَنْ صَلَّى الْعِشَاءَ فِي جَمَاعَةٍ كَانَ كَقِيَامِ نِصْفِ لَيْلَةٍ وَمَنْ صَلَّى الْفَجْرَ فِي جَمَاعَةٍ كَانَ كَقِيَامِ لَيْلَةٍ»  

[Machine] The Messenger of Allahﷺ said: "Whoever prays the evening and dawn prayers in congregation will be rewarded as if he had stood in prayer the whole night."  

قَالَ رَسُولُ اللَّهِ ﷺ «مَنْ صَلَّى الْعِشَاءَ وَالْفَجْرَ فِي جَمَاعَةٍ كَانَ كَقِيَامِ لَيْلَةٍ»  

The Messenger of Allah ﷺ said:Whoever prays ʿIshaʿ in congregation, it will be like spending half the night in prayer (qiyam) and whoever prays ʿIshaʿ and Fajr in congregation, it will be like spending the whole night in prayer.ʿ (Using translation from Aḥmad 491)   

قَالَ رَسُولُ اللهِ ﷺ مَنْ صَلَّى الْعِشَاءَ فِي جَمَاعَةٍ كَانَ كَقِيَامِ نِصْفِ لَيْلَةٍ وَمَنْ صَلَّى الْفَجْرَ فِي جَمَاعَةٍ كَانَ كَقِيَامِ لَيْلَةٍ أُخْرَى  

"مَنْ صَلَّى العِشَاءَ فِي جَمَاعَةٍ كَانَ كَقِيَامِ نِصْفِ لَيلِةٍ، وَمَنْ صَلَّى العِشَاءَ وَالفَجْرَ في جَمَاعَةٍ، كَانَ كَقِيَامِ لَيلَة".
