To Change the Intention of a Hired Fast Later
71. A person hires someone else to fast but avoid paying the money according to the contract. Is the hired person allowed to consider the performed fast to be qaḍā’ fast on behalf of a third person? In general, should I specify a fast to be on behalf of certain person at the beginning or I am allowed to determine the person even after completion of fast/prayer?
A: One should specify the intention of fast from the beginning. After completion of a ritual performed on behalf of a certain person, one cannot change it to be on behalf of someone else. In the given case, the person on whose behalf it was performed is free from the obligation, if any. The hiring person should pay his debt.
