فَإِنْ صَلَّى عَلَيْهِ غَيْرُ الْوَلِيِّ وَالسُّلْطَانِ: أَعَادَ الْوَلِيُّ.
Translation: If someone other than the guardian or ruler leads, the guardian may repeat the prayer.
This is a restricted right of the guardian where the first prayer was led by someone other than the ruler or the guardian.
It does not create a general entitlement for everyone to repeat a funeral prayer. The identity of the first leader is legally relevant.
