'Abdullah (b. Mas'ud) reported: I have seen the time when no one stayed away from prayer except a hypocrite, whose hypocrisy was well known, or a sick man, but it a sick man could walk between two persons (i. e. with the help of two persons with one on each side) he would come to prayer. And (further) said: The Messenger of Allah (ﷺ) taught us the paths of right guidance among which is prayer in the mosque in which the Adzan is called.

'Abdullah (b. Mas'ud) reported: He who likes to meet Allah tomorrow as Muslim, he should persevere in observing these prayers, when a call is announced for them, for Allah has laid down for your Prophet (ﷺ) the paths of right guidance, and these (prayers) are among the paths of right guidance. If you were to pray in your houses as this man why stays away (from the mosque) prays in his house, you would abandon the practice of your Prophet, and if you were to abandon the practice of your Prophet, you would go astray. No man purifies himself, doing it well, then makes for one of those mosques without Allah recording a blessing for him for every step he takes raising him a degree for it, and effacing a sin from him for it. I have seen the time when no one stayed away from it, except a hypocrite, who was well known for his hypocrisy, whereas a man would be brought swaying (due to weakness) between two men till he was set up in a row.

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 ﷺ 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.

550. Commentary: ➊ Lagging behind from the congregation has been described as one of the signs of the hypocrites, and this is even more serious than being a major sin (kabirah). ➋ The consequence of turning away from the Sunnahs of the Noble Prophet (sallallahu alayhi wa sallam) can ultimately lead to disbelief (kufr). «أعاذنا الله منه»
