Abu Huraira said, "I heard Messenger of Allah ﷺ saying, 'The reward of a prayer in congregation is twenty five times greater than that of a prayer offered by a person alone. The angels of the night and the angels of the day gather at the time of Fajr prayer.' " Abu Huraira then added, "Recite the Holy Book if you wish, for "Indeed, the recitation of the Qur'an in the early dawn (Fajr prayer) is ever witnessed." (17:78).  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ تَفْضُلُ صَلاَةُ الْجَمِيعِ صَلاَةَ أَحَدِكُمْ وَحْدَهُ بِخَمْسٍ وَعِشْرِينَ جُزْءًا وَتَجْتَمِعُ مَلاَئِكَةُ اللَّيْلِ وَمَلاَئِكَةُ النَّهَارِ فِي صَلاَةِ الْفَجْرِ ثُمَّ يَقُولُ أَبُو هُرَيْرَةَ فَاقْرَءُوا إِنْ شِئْتُمْ {إِنَّ قُرْآنَ الْفَجْرِ كَانَ مَشْهُودًا}  

Messenger of Allah ﷺ said, "The prayer in congregation is twenty seven times superior to the prayer offered by person alone."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ صَلاَةُ الْجَمَاعَةِ تَفْضُلُ صَلاَةَ الْفَذِّ بِسَبْعٍ وَعِشْرِينَ دَرَجَةً  

Messenger of Allah ﷺ said, "By Him in Whose Hand my soul is I was about to order for collecting firewood (fuel) and then order Someone to pronounce the Adhan for the prayer and then order someone to lead the prayer then I would go from behind and burn the houses of men who did not present themselves for the (compulsory congregational) prayer. By Him, in Whose Hands my soul is, if anyone of them had known that he would get a bone covered with good meat or two (small) pieces of meat present in between two ribs, he would have turned up for the ʿIsha' prayer.'  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ وَالَّذِي نَفْسِي بِيَدِهِ لَقَدْ هَمَمْتُ أَنْ آمُرَ بِحَطَبٍ فَيُحْطَبَ ثُمَّ آمُرَ بِالصَّلاَةِ فَيُؤَذَّنَ لَهَا ثُمَّ آمُرَ رَجُلاً فَيَؤُمَّ النَّاسَ ثُمَّ أُخَالِفَ إِلَى رِجَالٍ فَأُحَرِّقَ عَلَيْهِمْ بُيُوتَهُمْ وَالَّذِي نَفْسِي بِيَدِهِ لَوْ يَعْلَمُ أَحَدُهُمْ أَنَّهُ يَجِدُ عَرْقًا سَمِينًا أَوْ مِرْمَاتَيْنِ حَسَنَتَيْنِ لَشَهِدَ الْعِشَاءَ  

The Prophet ﷺ said, "No prayer is heavier upon the hypocrites than the Fajr and the ʿIsha' prayers and if they knew what is in them (in reward), they would have attended them, even if (it was) crawling. Certainly, I felt the urge to order the Mu'adh-dhin (call-maker) so that he would pronounce Iqama, then order a man to lead the people (in prayer), then take a flame of fire so that I burn (the houses) upon those who had not left for the prayer yet."  

قَالَ النَّبِيُّ ﷺ لَيْسَ صَلاَةٌ أَثْقَلَ عَلَى الْمُنَافِقِينَ مِنَ الْفَجْرِ وَالْعِشَاءِ وَلَوْ يَعْلَمُونَ مَا فِيهِمَا لأَتَوْهُمَا وَلَوْ حَبْوًا لَقَدْ هَمَمْتُ أَنْ آمُرَ الْمُؤَذِّنَ فَيُقِيمَ ثُمَّ آمُرَ رَجُلاً يَؤُمُّ النَّاسَ ثُمَّ آخُذَ شُعَلاً مِنْ نَارٍ فَأُحَرِّقَ عَلَى مَنْ لاَ يَخْرُجُ إِلَى الصَّلاَةِ بَعْدُ
