Sunan an-Nasa'i 837
It was narrated from Ibn 'Umar that the Messenger of Allah (ﷺ) said:
"Praying in congregation is twenty-seven times better than praying alone."
أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ صَلاَةُ الْجَمَاعَةِ تَفْضُلُ عَلَى صَلاَةِ الْفَذِّ بِسَبْعٍ وَعِشْرِينَ دَرَجَةً ‏"‏ ‏.‏
