"The Messenger of Allah said: 'The prayer of a man in congregation is twenty-seven levels more virtuous than a man's prayer on his own.'"

"The Messenger of Allah said: 'I was thinking of commanding that the call to prayer be given, then I would tell a man to lead the people in prayer, then I would go out with some other men carrying bundles of wood, and go to people who do not attend the prayer, and burn their houses down around them.'"

The Prophet said: "Whoever hears the call and does not come, his prayer is not valid, except for those who have an excuse."

"The Messenger of Allah said: 'The prayer of a man in congregation is higher than his prayer on his own by twenty-four or twenty-five levels."

"I said to the Prophet: 'I am an old man and blind; my house is far away, and I have no one to lead me. Is there any concession (for me not to have to attend the prayer in the mosque)?' He said: 'Can you hear the call?' I said: 'Yes.' He said: 'Then I do not find any concession for you.'"

"The Messenger of Allah said: 'Let men desist from failing to attend the congregation, otherwise I will burn their houses down.'"

"The Messenger of Allah said: 'If the people knew what (reward) there is in the 'Isha' prayer and fajr prayer, they would come even if they had to crawl.'"

"The Messenger of Allah said: 'The most burdensome prayers for the hypocrites are the 'Isha' prayer and the Fajr prayer. If only they knew what (reward) there is in them, they would come to them even if they had to crawl.'"

The Prophet said: "A muslim does not regularly attend the mosques to perform prayer and remember Allah, but Allah feels happy with him just as the family of one who is absent feels happy when he comes back to them."
