'Uthman b. 'Affan (narrated the mosque after evening prayer and sat alone. I also sat alone with him, so he said: 0, son of my brother, I heard the Messenger of Allah ﷺ say: He who observed the 'Isha' prayer in congregation, it was as if he prayed up to midnight, and he who prayed the morning prayer in congregation, it was as if he prayed the whole night.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ صَلَّى الْعِشَاءَ فِي جَمَاعَةٍ فَكَأَنَّمَا قَامَ نِصْفَ اللَّيْلِ وَمَنْ صَلَّى الصُّبْحَ فِي جَمَاعَةٍ فَكَأَنَّمَا صَلَّى اللَّيْلَ كُلَّهُ

(Using translation from Muslim 656a)  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «مَنْ صَلَّى الْعِشَاءَ فِي جَمَاعَةٍ فَكَأَنَّمَا قَامَ نِصْفَ اللَّيْلِ وَمَنْ صَلَّى الصُّبْحَ فِي جَمَاعَةٍ فَكَأَنَّمَا صَلَّى اللَّيْلَ كُلَّهُ»  

"مَنْ صَلَّى العِشَاءَ في جَمَاعَة فَكَأَنَّمَا قَامَ نصْفَ لَيلَةٍ، وَمَنْ صَلَّى الصُّبْحَ فِي جَمَاعَةٍ فَكَأَنمَا صَلَّى اللَّيلَ كلَّهُ".  

"مَنْ صَلَّى العِشَاءَ الآخرَةَ في جَمَاعَةٍ، فَكَأَنَّمَا صَلَّى اللَّيلَ كُلَّهُ، وَمَنْ صَلَّى الغَدَاةَ فِي جَمَاعَةٍ فَكَأَنَّمَا صَلَّى النَّهَارَ كُلَّهُ".
