وَعَلَيْهِ الْقَضَاءُ
Translation: And a make-up Hajj is required of him.
Al-qadaʾ here means undertaking a make-up Hajj because the earlier one became invalid. A financial offering alone does not replace this duty.
Keep the three obligations distinct: continue the current rites, give the prescribed sheep offering, and undertake a make-up Hajj. This brief clause does not stipulate a specific calendar year for the make-up pilgrimage.
