وَمَنْ جَعَلَ مِنْهُمْ وَجْهَهُ إِلَى وَجْهِ الْإِمَامِ: جَازَ وَيُكْرَهُ.
Translation: If a follower faces the imam face-to-face, the prayer is valid but disliked.
Jāza establishes validity, while yukrahu identifies dislike in this arrangement.
The ruling is neither invalidity nor unrestricted permissibility: validity and dislike are separate legal judgments that can coexist.
