What is the ruling if an obligatory part of the prayer is intentionally omitted before the concluding salutation?

Al-Mughni
Book of Prayer
Primary text
If an obligatory part of the prayer is intentionally omitted before the concluding salutation (Taslim), the prayer is invalidated because an intentional omission of an obligatory element occurred within the ritual structure.
Supporting text
If the obligatory part is omitted after the Taslim, the prayer is not invalidated, as the reparation is considered an external rectification of the worship, similar to reparations in Hajj.
