وَإِذَا اشْتَرَكَ حَلَالَانِ فِي قَتْلِ صَيْدِ الْحَرَمِ: فَعَلَيْهِمَا جَزَاءٌ وَاحِدٌ.
Translation: If two people not in ihram jointly kill sanctuary game, they together owe one compensation.
Al-halalan denotes two individuals outside ihram. The protected animal is sanctuary game, identified by place.
Al-Quduri says fa-ʿalayhima jazaʾun wahid: one shared compensation for both. That is different from the preceding clause, under which each muhrim owes a full penalty.
