What is the difference between congregational prayer at home and in the mosque in terms of validity and sin, and what is the extent of the sin if it exists? And does Allah approve of a person who regularly performs the Sunnah and supererogatory prayers, and relies on Allah's mercy, but does not pray in the mosque due to psychological and physical illnesses, and because his household members do not pray unless he leads them?

A Muslim's walk to the mosque, its maintenance, and waiting for prayer therein carry great virtue. The Muslim who mixes with people and endures their harm is better than one who does not. A Muslim should strive to overcome psychological ailments and consult trustworthy doctors.

Scholars differ on the obligation of congregational prayer in the mosque. The majority say it is not obligatory in the mosque. Your congregational prayer at home is valid according to the majority, and there is no sin upon you, even if you miss out on the greater virtue. It is preferable to strive for congregational prayer in the mosque to avoid disagreement and seek complete reward.
