Rule 86...

Rule 86: If the will of the deceased stipulates that an agent be appointed to perform an obligatory pilgrimage on his behalf for a given wage, it is obligatory to act upon it. The remuneration should be paid from the gross estate, if it does not exceed what is commonly held as acceptable. However, if it does, the excess must be settled from the one-third bequeathable portion.

Rule 87: If the will of the deceased stipulates that pilgrimage be performed on his behalf from an identified property, and it is in the knowledge of the executor that there is a liability of khums or zakah on the property, these must first be paid from it.
