Hadith: Praying in congregation is twenty-seven degrees better than praying alone

عن عبد الله بن عمر رضي الله عنهما أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ: «صلاةُ الجَمَاعَة أَفضَلُ من صَلاَة الفَذِّ بِسَبعٍ وعِشرِين دَرَجَة».
[صحيح] - [متفق عليه]

‘Abdullāh ibn ‘Umar (may Allah be pleased with him) reported that the Messenger (may Allah's peace and blessings be upon him) said: "Praying in congregation is twenty-seven degrees better than praying alone."
[Authentic hadith] - [Narrated by Bukhari & Muslim]

Explanation

This Hadīth shows the virtue of praying in congregation over praying alone, because praying in congregation - due to what it contains of great, immense benefit - is more virtuous and increases the reward by twenty-seven times more than praying alone. This is due to the great gap between the two in terms of achieving the target. Without a doubt, whoever misses out on this great profit is deprived.
