The excellence of performing prayers in congregation

Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (PBUH) said, “A man’s Salat in congregation is twenty-five times more rewarding than his Salat at home or in his shop, and that is because when he performs his Wudu’ properly and proceeds towards the mosque with the purpose of performing Salat in congregation, he does not take a step without being raised a degree (in rank) for it and having a sin remitted for it, till he enters the mosque. When he is performing Salat, the angels continue to invoke Blessings of Allah on him as long as he is in his place of worship in a state of Wudu’. They say: `O Allah! Have mercy on him! O Allah! Forgive him.’ He is deemed to be engaged in Salat as long as he waits for it.”[Al-Bukhari and Muslim]. 

“O Messenger of Allah! I have no one to guide me to the mosque .” He, therefore, sought his permission to perform Salat (prayer) in his house. He (PBUH) granted him permission. When the man turned away, he called him back, and said, ” Do you hear the Adhan (call to prayer)?” He replied in the affirmative. The Messenger of Allah (PBUH) then directed him to respond to it.[Muslim].

Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (PBUH) said,“By Him in Whose Hand my life is, I sometimes thought of giving orders for firewood to be collected, then for proclaiming the Adhan for Salat. Then I would appoint an Imam to lead Salat, and then go to the houses of those who do not come to perform Salat in congregation, and set fire to their houses on them .”[Al-Bukhari and Muslim].

Ibn Mas`ud (May Allah be pleased with him) reported: He who likes to meet Allah tomorrow (i.e., on the Day of  Requital) as a Muslim, should take care and observe the Salat when the Adhan is announced for them. Allah has expounded to your Prophet (PBUH) the ways of right guidance, and these ( the prayers) are part of the right guidance. If you have to perform Salat in your houses, as this man who stays away (from the mosque ) and performs Salat in his house, you will abandon the Sunnah (practice) of your Prophet (PBUH), and the departure from the Sunnah of your Prophet (PBUH) will lead you astray. I have seen the time when no one stayed behind except a well-known hypocrite. I also saw that a man was brought swaying ( on account of weakness) between two men till he was set up in a row (in the mosque).[Muslim].
