Must the cafeteria be closed during prayer times, and is its owner sinful for not closing it?

The ruling on closing a shop to perform prayer in the mosque has been previously explained. If you close your cafeteria and go to pray, you have fulfilled your obligation, and you will not be held accountable for the failure of others, for Allah says: "And every soul earns not [anything] except for itself, and no bearer of burdens will bear the burden of another." (Al-An'am: 164). Thus, every soul is recompensed for its own deeds and does not bear the sin of another.
