Ibn Umar reported Messenger of Allah ﷺ assaying: Prayer said in a congregation is twenty-seven degrees more excellent than prayer said by a single person.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ
" صَلاَةُ الْجَمَاعَةِ أَفْضَلُ مِنْ صَلاَةِ الْفَذِّ بِسَبْعٍ وَعِشْرِينَ دَرَجَةً " .
