In the name of Allah al-Rahman al-Rahim
Jumu’ah prayer is an obligation in and of itself on the day of Friday and not a substitute for Zhuhr.
“And it [salat al-Jumu’ah] is an obligation in and of itself.”
[Radd al-Muhtar ‘ala al-Durr al-Mukhtar]
The four sunnah prayed before Jumu’ah are with the intention of Jumu’ah. One intends: I intend to pray four prior sunnah raka’ats of Jumu’ah, for the sake of Allah Most Transcendent. After the 2 fards of Jumu’ah one intends: I intend to pray four post sunnah raka’ats of Jumu’ah for the sake of Allah Most Transcendent.
Thus both the four sunnahs before and after Jumu’ah are to be offered with the intention of them being prior and post sunnahs of Jumu’ah. As is mentioned in Nur al-Idah:
“And [4 sunnah mu’akkadah raka’ats] before Jumu’ah and [4 sunnah mu’akkadah rak’ats] after it [Jumu’ah] .”
[Nur al-Idah wa Najat al-Arwah]
