وَيَمْضِي فِي الْحَجِّ كَمَا يَمْضِي مَنْ لَمْ يُفْسِدْ حَجَّهُ
Translation: He continues the Hajj rites as a person whose Hajj has not been invalidated would continue them.
Invalidity does not mean the pilgrim may immediately abandon ihram or stop the rites. Al-Quduri expressly requires continuing the pilgrimage acts.
Completing the remaining actions is not the same as turning the invalid Hajj into a valid one. The obligation of a make-up Hajj follows in the next clause.
