Ritual 94

If the will of the deceased stipulates that an obligatory pilgrimage be performed on his behalf, and it becomes known that it was Hajjatul Islam, the expenses incurred must be paid from the gross estate, unless he has expressly directed that the expenses be settled from his bequeathable one-third. If it becomes known to the person so directed that pilgrimage was other than Hajjatul Islam, or if there is doubt, the expenses must be paid from the one-third.
