Case 1: a violation that expressly requires one dam from a mufrid entails two dam offerings for a qarin under this clause.
Case 2: if an action is assigned only charity, this wording alone cannot be used to convert it into two full offerings.
Case 3: an act with no penalty in the relevant source cannot acquire an invented dam solely because the pilgrim is a qarin.
The condition “for which a mufrid owes a dam” governs the entire sentence.
