Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "A man's praying in congregation is superior to his praying alone by twenty-odd degrees." In one narration the words are: "It is superior by twenty-five degrees." In one narration the words are: "All of those degrees will be like his prayer." In one narration the words are: "Each of them will be like his praying in his own house."
Imam Ahmad, Imam Abu Ya'la, Imam al-Bazzar and Imam al-Tabarani in al-Mu'jam al-Kabir and al-Mu'jam al-Awsat recorded it, and it is he who recorded the words "in his own house"; he recorded these words in al-Mu'jam al-Kabir. The narrators of Imam Ahmad are thiqat (trustworthy).
