The one who continues his visits (going and coming) to the mosque does lay his hands upon one of eight benefits:
(Getting to know) one of the decisive verses.
Finding a beneficial brother.
Fresh knowledge.
A mercy waiting for him.
A word leading to the guidance.
An admonition averting from sin.
Not committing sin out of scheme.
Not committing sin for the fear of Allah.
Imam Hassan (as)
