If Fajr Namaz is missed on a Friday, can we offer its Qaza after doing the Ghusl of Juma or do we need to perform Wuzu for it?
We must try our best to perform every Prayer within its time and never miss any Prayer as much as we can. If God firbid, Fajr Namaz is missed, we must perform its Qaza as soon as we can. There is no condition to perform Ghusl of Jum’a before performing the Qaza although Ghusl Jum’a is very great recommended Ghusl, but you can perform the Qaza of Fajr with Wudhu only or after Ghusl Jum’a if you wish but Ghusl Jum’a is not obligatory nor a condition for Qaza Namaz.
Wassalam.
