The Book On The Mosques And The Congregations
The Virtue Of Prayer In Congregation
حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنْ هِلاَلِ بْنِ مَيْمُونٍ، عَنْ عَطَاءِ بْنِ يَزِيدَ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ صَلاَةُ الرَّجُلِ فِي جَمَاعَةٍ تَزِيدُ عَلَى صَلاَتِهِ فِي بَيْتِهِ خَمْسًا وَعِشْرِينَ دَرَجَةً .
It was narrated that Abu Sa'eed Al-Khudri said: "The Messenger of Allah said: 'the prayer of a man in congregation is twenty-five levels higher than his prayer in his home.'"
