Can you pray Friday prayer before Zawaal?
You can pray the Friday prayer before Zawaal. This is the opinion of the Hanaabilah. This is not the opinion of the majority of scholars.
The Hanaabilah say that the time for the Friday prayer begins when the time for Eid prayer begins.
On Eid you pray Eid prayer. You pray it at a time which is before Zawaal. That is the same time you can pray Friday prayer on Friday according to the Hanaabilah.
The majority disagrees with the Hanaabilah. Being the majority does not mean you are right. The minority can be correct. Being correct depends on which opinion is closer to the Qur'aan and Sunnah.
The Hanaabilah maintain that you can pray the Friday prayer before Zawaal. The time for Friday prayer is the same as the time for Eid prayer on the day of Eid.
