What is the Islamic term for the science of calculating inheritance shares?

Explanation

– Ilm al-Fara’id is the specialized Islamic science dealing with the calculation and precise distribution of inheritance shares among the various eligible heirs of a deceased person.
– This field draws directly from detailed Quranic verses and Hadith, establishing fixed shares for specific categories of relatives depending on their relationship to the deceased.
– For exams, note that Wasiyyah refers separately to a will, which in Islamic law is generally limited to no more than one-third of a person’s total estate.
