عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ: ((تَفْضُلُ صَلَاةُ الْجَمَاعَةِ عَلَى الْوَحْدَةِ سَبْعًا وَعِشْرِينَ دَرَجَةً أَوْ خَمْسًا وَعِشْرِينَ))
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: The congregational prayer has twenty-seven or twenty-five degrees more excellence than the prayer performed alone.
