أرأيت لو كان على أبيك دين فقضيته أما كان يجزئك؟
Suppose your father owed a debt and you paid it: would that not discharge it on his behalf?
A woman asked about performing pilgrimage for her father, and the response drew a comparison with discharging another person's debt. The original case is the recognized discharge of a debt by someone else. The new case asks whether pilgrimage can, under appropriate conditions, be performed on another person's behalf.
The comparison clarifies the reasoning without asserting that debts and pilgrimage are identical in every respect. The independent legal conditions governing pilgrimage still apply.
