Is it obligatory to close an internet café at the time of Friday prayer, and what is the required duration of closure before and after the prayer?

What is forbidden for those obligated to attend Jumu'ah (Friday prayer) is selling at the time of the adhan (definition) (call to prayer) that follows the Imam's seating on the minbar until the prayer concludes. However, closing the shop is not obligatory. It is recommended for the ruler to make the market people stay in their shops during the time of Jumu'ah prayer. It is permissible for the wife to remain in the shop if there is no seclusion with non-mahram (definition) men. However, she is not permitted to deal with those who are obligated to attend Jumu'ah at this time. It is permissible to sell to women, travelers, and others who are not obligated to attend Jumu'ah in the markets.
