وَالْمُحْصَرُ بِالْحَجِّ إِذَا تَحَلَّلَ: فَعَلَيْهِ حَجَّةٌ، وَعُمْرَةٌ.
Translation: An obstructed Hajj pilgrim who exits ihram owes one Hajj and one Umrah.
Having the obstruction offering slaughtered and leaving ihram does not necessarily discharge every obligation generated by the interrupted pilgrimage.
Al-Quduri explicitly assigns one Hajj and one Umrah to this case. The additional Umrah is part of this classical legal ruling, not merely optional extra worship.
