Mujahid said:

"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.'"

قَالَ مُجَاهِدٌ وَسُئِلَ ابْنُ عَبَّاسٍ 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 ‏.‏
