the Prophet said: "I was about to order my boys to collect bundles of firewood, then order Salat to be held, then burn (the homes) of the people who did not attend the Salat."  

عَنِ النَّبِيِّ ﷺ قَالَ لَقَدْ هَمَمْتُ أَنْ آمُرَ فِتْيَتِي أَنْ يَجْمَعُوا حُزَمَ الْحَطَبِ ثُمَّ آمُرَ بِالصَّلاَةِ فَتُقَامَ ثُمَّ أُحَرِّقَ عَلَى أَقْوَامٍ لاَ يَشْهَدُونَ الصَّلاَةَ  

"Ibn Abbas was asked about a man who fasted during the day and stood (in prayers) during the night, but he did not attend the Friday prayer nor congregational prayer. He replied: 'He is in the Fire.'"  

عَنْ رَجُلٍ يَصُومُ النَّهَارَ وَيَقُومُ اللَّيْلَ لاَ يَشْهَدُ جُمُعَةً وَلاَ جَمَاعَةً قَالَ هُوَ فِي النَّارِ قَالَ حَدَّثَنَا بِذَلِكَ هَنَّادٌ حَدَّثَنَا الْمُحَارِبِيُّ عَنْ لَيْثٍ عَنْ مُجَاهِدٍ قَالَ وَمَعْنَى الْحَدِيثِ أَنْ لاَ يَشْهَدَ الْجَمَاعَةَ وَالْجُمُعَةَ رَغْبَةً عَنْهَا وَاسْتِخْفَافًا بِحَقِّهَا وَتَهَاوُنًا بِهَا
