Abdullah bin Masud said: Persevere in observing these five times of prayer where the announcement for them is made, because they are from the paths of right guidance. And Allah, the Might, the Majestic, has laid down for his prophet صلی اللہ علیہ وسلم the paths of right guidance. I have seen the time when no one stayed away from prayer except a hypocrite whose hypocrite was well known. I witnessed the time when a man would be brought swaying between two men till he was set up in the row (of the prayer). Every one of us has a mosque of his in his house. If you were to pray in your houses and stay from your mosques. You would abandon the Sunnah (practice) of your prophet, and if you were Abandon the Sunnah (Practice) of your Prophet, you would become an unbeliever.

Narrated Abdullah ibn Abbas: If anyone hears him who makes the call to prayer and is not prevented from joining the congregation by any excuse--he was asked what an excuse consisted of and replied that it was fear or illness--the prayer he offers will not be accepted from him.
