عَنْ عُثْمَانَ بْنِ عَفَّانَ رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((مَنْ صَلَّى الْعِشَاءَ فِي جَمَاعَةٍ فَهُوَ كَمَنْ قَامَ نِصْفَ اللَّيْلِ، وَمَنْ صَلَّى الصُّبْحَ فِي جَمَاعَةٍ فَهُوَ كَمَنْ قَامَ اللَّيْلَ كُلَّهُ))
It is narrated from Sayyiduna Uthman bin Affan (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whoever performs the ‘Isha prayer in congregation, it is as if he has stood in prayer for half the night, and whoever performs the Fajr prayer in congregation, it is as if he has stood in prayer for the entire night.
