وَمَنْ صَلَّى الظُّهْرَ فِي مَنْزِلِهِ يَوْمَ الْجُمُعَةِ قَبْلَ صَلَاةِ الْإِمَامِ، وَلَا عُذْرَ لَهُ: كُرِهَ لَهُ ذَلِكَ، وَجَازَتْ صَلَاتُهُ.
Translation: Someone without an excuse who prays Zuhr at home before the imam conducts Jumuah acts reprehensibly, although the Zuhr prayer is valid in the stated ruling.
A person obligated to attend should not avoid Jumuah. The text nevertheless distinguishes the disliked choice of performing Zuhr beforehand from the legal validity of that Zuhr.
