The time of the prohibition of gathering in circles on Friday

Your Eminence! Regarding the prohibition of gathering in circles on Friday, does it refer to immediately before the prayer, or after the Fajr prayer?
It appears that gathering in circles before people arrive at the mosque is permissible. The Messenger of Allah (peace and blessings be upon him) prohibited it so that they would not crowd the people coming to the prayer, and usually, there are no people after Fajr.
