وَمَضَى فِيهَا وَقَضَاهَا وَعَلَيْهِ شَاةٌ
Translation: He continues that Umrah, makes it up, and owes one sheep.
The invalid Umrah must not simply be abandoned. Al-Quduri lists three duties: finish the present Umrah rites, perform a make-up Umrah, and offer one sheep.
The pattern resembles making up an invalid Hajj, but the specific obligation here is a make-up Umrah, not a Hajj.
