The stronger position regarding the beginning of the time for the Friday prayer?

The Shaykh : But there is a middle opinion that says it is valid at six o'clock, based on the hadith of Abu Hurayrah: "Whoever goes out in the first [hour] then the fifth, and what is close to the fifth?"
An egg [of time], so when the imam comes out, meaning it ends, the angels are present listening to the dhikr. The imam's presence, according to the calculation of Abu Hurayrah, is at six o'clock. For this reason, al-Muqaffa (may Allah have mercy on him) preferred in al-Mughni, and he is one of the great companions of Imam Ahmad, that it is not valid before six o'clock, as many of the companions held, including al-Khiraqi, that it is not valid before six o'clock.
So at the beginning of the day, it is not valid. This is the stronger position: that it is not valid at the beginning of the day, but rather it is valid from six o'clock. Also, according to the position that it is valid at six o'clock, it is better for it to be after the sun has passed its zenith, in accordance with the majority of scholars. Yes.
