فإن السعي حسن بواسطة كونه مفضيا إلى أداء الجمعة
Going to Friday prayer is good insofar as it leads to the performance of the Friday prayer.
Someone who is not legally required to attend Friday prayer does not, merely through that duty, become obliged to undertake the journey. For a person required to attend and not already at the place of worship, getting there may be a necessary means.
Going to the mosque is thus considered as an instrument of the Friday obligation, not as an independently identical duty in every circumstance.
