"The houses of the Ansar were far from the mosque and they wanted to move closer. Then the following Verse was revealed: 'We record that which they send before (them), and their traces.'" [Ya-Sin: 12] He said: So they remained (where they were)."
"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.'"
"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.'"
They heard the Prophet say on his pulpit: "People should desist from failing to attend the congregations, otherwise Allah will seal their hearts, and they will be among the negligent."
