Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “The prayer of a man in congregation is twenty five times better than prayer in his home or shop. When he performs ablution in a good manner and leaves to the mosque only to perform prayer, then his every step will raise him a degree and expiate a sin until he enters the mosque. When he is performing prayer, the angels send blessings upon him for as long as he remains in his place of prayer. They say: O Allah, bless him and have mercy upon him. One of you continues to be in prayer as long as he is waiting for prayer.”
Abu Huraira said, “Recite the verse if you wish: And the recitation at dawn, for the recitation at dawn is witnessed.” (17:78)

عن أبي هريرة قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ صَلَاةُ الرَّجُلِ فِي الْجَمَاعَةِ تُضَعَّفُ عَلَى صَلَاتِهِ فِي بَيْتِهِ وَفِي سُوقِهِ خَمْسًا وَعِشْرِينَ ضِعْفًا وَذَلِكَ أَنَّهُ إِذَا تَوَضَّأَ فَأَحْسَنَ الْوُضُوءَ ثُمَّ خَرَجَ إِلَى الْمَسْجِدِ لَا يُخْرِجُهُ إِلَّا الصَّلَاةُ لَمْ يَخْطُ خَطْوَةً إِلَّا رُفِعَتْ لَهُ بِهَا دَرَجَةٌ وَحُطَّ عَنْهُ بِهَا خَطِيئَةٌ فَإِذَا صَلَّى لَمْ تَزَلْ الْمَلَائِكَةُ تُصَلِّي عَلَيْهِ مَا دَامَ فِي مُصَلَّاهُ اللَّهُمَّ صَلِّ عَلَيْهِ اللَّهُمَّ ارْحَمْهُ وَلَا يَزَالُ أَحَدُكُمْ فِي صَلَاةٍ مَا انْتَظَرَ الصَّلَاةَ
قَالَ أَبُو هُرَيْرَةَ اقْرَءُوا إِنْ شِئْتُمْ وَقُرْآنَ الْفَجْرِ إِنَّ قُرْآنَ الْفَجْرِ كَانَ مَشْهُودًا
