Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah ﷺ said, "Prayer in congregation is better than the prayer of a man by himself by twenty-seven degrees."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ صَلاَةُ الْجَمَاعَةِ تَفْضُلُ صَلاَةَ الْفَذِّ بِسَبْعٍ وَعِشْرِينَ دَرَجَةً
