وَيَجُوزُ لِلْعَبْدِ وَالْمُسَافِرِ وَالْمَرِيضِ أَنْ يَؤُمُّوا فِي الْجُمُعَةِ.
Translation: An enslaved person, traveller or ill person may lead the Friday prayer.
Being exempt from the duty to attend is not by itself disqualification from leading it, provided the other conditions for valid imamate and Jumuah are fulfilled.
